BUYER'S GUIDE

Best rear bike lights 2024 — boost your day & night visibility with a bright beam at the back

Running one of the best rear bike lights with plenty of lumens should mean all but the most idiotic drivers will notice you from a good distance

This article contains links to retailers. Purchases made after clicking on those links may help support road.cc by earning us a commission but all of our reviews are fully independent. Find out more about road.cc buyer's guides.

Over the years we've clocked up thousands upon thousands of cold, dark winter road miles to test hundreds of rear lights. From brilliant budget beamers to retina-ripping radiants that demand even the dopiest driver's attention, here are some of the best rear bike lights you can buy, with quick links to our very top picks listed below this paragraph, plus plenty more road.cc-recommended rear lights further down the page. 


A rear light is a legal requirement when cycling at night, and using one that's brighter than the legal minimum seems like a sensible way of helping drivers see you — or at least defanging 'but I didn't see them' excuses. The best bike rear lights have long run-times, can be seen from a good distance, and are sufficiently tough and waterproof to fend off day-to-day abuse.

Rear lights for cycling universally use one or more red light-emitting diodes (LEDs) to generate their light. LEDs are very efficient, putting out lots of light for modest electrical power, which makes them cheap to run but effective at boosting visibility. Most rear bike lights are now rechargeable, taking power from a USB source like a standalone charger or your office computer. Battery-powered lights are still available, and have their adherents who appreciate being able to revive a dead light at any filling station or corner shop.

A flashing red light says 'bike' to most drivers; we recommend using a constant light as well so your position can be easily followed. It can be hard to track the position of a flasher on an otherwise unlit minor road. Rear bike lights are increasingly intended as day-time safety lights too, with super-bright flash or pulse modes designed to be impossible for drivers to ignore. They can be very annoying to other riders though; please use them only when necessary.

How we review rear bike lights

While we don't deploy the famous road.cc Beam Comparison Engine to test rear lights, the procedure for reviewing rear lights is much the same as front beams round these parts. Our reviewers, with centuries of riding experience between them, use products for at least a month before writing up their findings and coming up with final verdicts.

Rear lights are assessed on construction quality, design, ease of use, waterproofing, weight, durability, brightness and value. We'll always take price into consideration when scoring a rear light on its features and specification: e.g. a £15 light won't get slammed for its lack of modes and beam power compared to a £100 one. With a huge review archive, we can keep it fair by comparing like-for-like. 

Why you can trust us

All products included in road.cc buyer's guides will be things we've reviewed in full, or are highly recommended among multiple members of the team (the latter scenario is rare, but occasionally happens if it's an updated product we can't get hold of for review, or something that has been discontinued).

Because we've reviewed a lot of rear lights over the years, the ones you'll find in this guide will all have scored 8/10 or more to be considered for inclusion. No matter how big the brand is or how many units it's shifted on Amazon, it won't make it into this guide if the review score was average or worse... which sometimes annoys our commercial team and advertisers, but that's the law of the land. 

Of course, the road.cc team members who write our guides are all experienced cyclists too. This means you can be sure we've made carefully considered product selections, and the advice you'll find at the bottom of the page is based on our real-world experience. 

If you want to see our top picks of back, front and combined lights all in one place, you can also check out our overall guide to the best bike lights. Just looking for a front beam? Head on over to our guide to the best front bike lights instead. 

The best rear bike lights: our top picks

Exposure Boost-R with ReAKT and Peloton

Exposure Boost-R with ReAKT and Peloton

9
Best rear bike light overall
Buy now for £74.99 from Tweeks Cycles
Bright
Several modes
Good runtimes
Pricey

Exposure's TraceR with ReAKT and Peloton rear light impressed us previously and in creating the new Boost-R, Exposure has taken the highly regarded Trace-R and doubled the runtimes while adding just 10g in weight. 

You get a beaming 80-lumen max output, with six modes that dictate how much burn time you have, from 6 hours in the brightest static mode to 48 hours on the lowest flash mode, plus DayBright pulse mode. 

ReAKT is probably the best feature of the lot, adapting to the light conditions at the time, and flaring up when it senses that the rider is braking. Additionally, the Peloton feature recognises when there is a front bike light behind you and dims itself to save dazzling the following rider. 

Lezyne Strip Drive 300+ LED Rear Light

Lezyne Strip Drive 300+ LED Rear Light

Our top super-bright rear light recommendation
Buy now for £30 from Merlin Cycles
Wide range of powerful modes
Huge run-times
IPX7 waterproofing
Easy to use
It's quite chunky

No-nonsense, easy-to-use and highly capable - that's how our reviewer summarised Lezyne's revamped Strip Drive with a huge 300 lumens in its max setting, and loads of other useful modes for all use cases at a sensible price. 

In the lowest 5-lumen mode you can get a huge 80 hours out of this light, and in the 60-lumen 'always on' mode its still over five hours, enough for a week of commuting or more for most of us. It's easy to use and fits almost any seatpost with the flexible back and stretchy rubber strap to attach it. 

If you want to go even brighter still, there's always the Lezyne Zecto Drive Max 400+ that also scored well in its road.cc review - but the Strip Drive edges it for the huge run times and ease of use. You don't get any smart braking tech or extras beyond the super bright light, but the very good price reflects that. 

Knog Plus Rear Light, Black

Knog Plus Rear Light, Black

9
Cheapest road.cc-recommended rear light
Buy now for £14.99 from Chain Reaction Cycles
Light and slim
Easy to detach
Highly visible
Cable-free charging
A bit wobbly on aero posts

If you're a time triallist or hill climber, or just want some brightness without adding weight to your bike set-up, then this very affordable beam from Knog is well worth a look. As well as been light on the wallet, it's also light in weight too, coming in at a diddy 18g.  

Our reviewer described it as "an impressively simple light that weighs almost nothing". Pumping out 20 lumens, it's bright enough for a useful visibility boost. The mount is magnetic, and there's a USB port built into it so you don't need a cable for charging. 

Burn time is two hours in steady mode which isn't huge, but on eco flash you can get 40 hours out of it according to Knog. There are five modes to choose from, and you can't really go wrong for this price.  

Giant Recon TL 200 rear light

Giant Recon TL 200 rear light

9
Best value rear bike light
Buy now for £27.99 from Cycle Store
Bright
Compact
Good run-times
Waterproof, reliable and durable
Easy to use
Tricky to separate light from bracket (but at least you won't lose it on bumpy ground)

Neither cheap nor expensive, Giant's Recon is worth every penny if you value brightness, reliability and good run times. It's also waterproof, durable and easy to use. 

This compact light is great for day or night, and it kicks out 200 lumens on the max setting. 270 degrees of visibility thanks to two strips in the side of the light unit ensures you're visible to motorists approaching from side streets. 

You can mount it vertically or horizontally, and charging is via USB. There are seven modes to choose from, and even the high flash mode provides an impressive six hours of run time. 

If your budget is tighter or you simply don't need this much brightness and extra settings, we also highly recommend the Giant Recon TL 100

Brightside Bright, Amber and Sideways

Brightside Bright, Amber and Sideways

9
Best sidelight for extra visibility
Buy now for £22.99 from Halfords
Extra dimension of visibility
Well-made

While it's not actually a rear light, Brightside's eponymous light deserves a mention for the clever way it provides extra visibility on top of your front and rear beams. 

It's essentially  a well-built double-ended side light at a good price that attaches easily to your frame, and gives you an extra dimension of visibility to other road users approaching you from the side. Bright 15-lumen Cree LEDs at each end attract attention.

The Brightside has filled a gap in the market (a quick internet search only unearthed the Brightside and the Cateye Orbit Spoke lightset) in a bid to reduce the instances of SMIDSY (sorry mate I didn't see you) incidents. With too many accidents happening at junctions and roundabouts, the light is designed to give you all-round visibility to motorists approaching from your side – Brightside, not broadside.

Great rear light
Alerts you about overtaking objects well before you can see or hear them
Expensive

The Garmin Varia RTL515 is a very good rear light with a reliable alert system for being overtaken.

The radar system alerts you to cars behind you, and while you might be thinking that you don't need a radar system, Iwein felt that it made his riding safer because it alerted him to overtaking objects before he could see or hear them.

The rear light is among the best in class in terms of flash pattern and brightness too with a battery life of around 16 hours on day flash mode.

ETC R65 65 Lumen USB Rear Light

ETC R65 65 Lumen USB Rear Light

8
Buy now for £15.99 from Ebay
Solid mount
Easy to use
Useful modes
Bright
Waterproofing a little weak

Most of the lights we review are more expensive than £15.99, and of those that are close, few are as bright. The ETC R65 USB Rear Light is a well-made and effective light that lasts well between charges and at full power, and is easily bright enough to be seen in daylight. 

The light has six modes, cycled with a single press, so it's easy to choose. You get high and low solid beams, two speeds of flash, a mode that combines very fast flashes with bursts of solid beam, and a smoothly rising and falling pulse.

ETC doesn't claim any run-times, but in the solid 65-lumen mode it lasts around 90 minutes, and everything else runs usefully longer than that – flashing mode is easily good for a typical week's commuting, and unless you're running that full power solid mode it's dependably fit-and-forget rather than charge-every-ride.

Cateye Viz 450 Rear Light

Cateye Viz 450 Rear Light

8
Buy now for £37 from Merlin Cycles
Cateye lights tend to be solidly made and last for years
Very high output when you really need that...
...other effective (and less offensive) modes for when you don't
Generally easy to use, fit and live with
Overkill for most use-cases, and most will find all the illumination they need in cheaper models

As a whole, we've found that Cateye lights tend to be well-made units that chuck out lots of light and last for years and the Cateye Viz 450 Rear Light is no exception. 

Cateye's Viz 450 rear light can throw out an extremely bright beam, although the full power is reserved for an intermittent flash in the 'Daytime Hyperflash' mode. It combines the all-round visibility from Cateye's earlier Rapid models with a focused beam that will have you seen from hundreds of metres back.

As the name suggests, Cateye's Viz 450 rear light can emit an extremely bright beam—450 lumens. In some specific use cases, you might appreciate this level of power, but for most cyclists, it can be considered overkill.

Gemini Juno 100 rear light

Gemini Juno 100 rear light

8
Buy now for £34.9 from Ebay
Very bright, but kind on the eyes
Versatile mount
Easy to use
Run-times shorter than claimed
Rotating mount could be better

The Gemini Juno 100 is a simple, easy to use rear light with few frills, but it does pack some useful features, including a 30 COB (chip-on-board) LED lighting array that's super-bright without melting eyeballs, and a clip mount that allows it to be attached on or off the bike in a variety of ways.

The oval arrangement of LEDS gives the light a distinctive shape that certainly stands out from the usual lighting crowd, and thanks to the ability to rotate around its base 90 degrees, it can be orientated either in line with your seatpost, or perpendicular to it.

The curved lens also gives the light decent side visibility as well, which is a bonus. Although 100 lumens max might not sound as powerful as some, even in bright daylight it really stands out – I honestly don't think you need any more than this to stand out, unless you want to be really obnoxious.

Techalogic CR-1 Rear Light with HD Wide Angle Camera

Techalogic CR-1 Rear Light with HD Wide Angle Camera

8
Buy now for £99.95 from Techalogic
Good value
Simple to operate
Includes various mounting options
Weatherproof
Has a rear view mirror mode
Chunky looks
Buttons flat and hard to find

The Techalogic CR-1 Rear Light with HD Wide Angle Camera is a decent light and a good camera too, at least for safety use. 

The light consists of a stack of five LEDs and at the top, you'll find the camera lens, which is protected by a flush-fitted cover designed to minimise the risk of scratching. The camera captures footage at a resolution of 1920x1080, recording at a frame rate of 30 frames per second. With its wide 120-degree field of view, it covers the entire road width, and during playback, it consistently provides sharp images.

The light offers five different modes, consisting of four flashing modes and one steady mode. When solely using the camera, the battery lasts approximately 7 hours, whereas when using both the camera and the flashing light, it provides around 5.5 hours of runtime.

Kryptonite Incite XR USB Rear light

Kryptonite Incite XR USB Rear

Buy now for £18.75 from Fawkes Cycles
Bright
Easy to operate
Lacks punch for fog

The Kryptonite Incite XR USB Rear light is well suited to being your weekday commuting bike light thanks to a solid run-time, easy operation and good side visibility.

The Incite XR has five modes lasting for around 20 hours in the high steady flash mode and up to 36 hours in eco mode. 

Usually, we see the brightness of bike lights measured in lumens. Kryptonite measures its rear lights in Lux and this Incite XR is given a value of 0.06. In real terms, I found the Incite XR to be perfectly bright enough for city commuting.

Bryton Gardia R300L Rear View Bike Radar Tail Light

Bryton Gardia R300L Rear View Bike Radar Tail Light

8
Buy now for £119.99 from Halfords
Effective radar coverage
Easy pairing with head units
Simple to operate
Smart light functions
Not 100% on picking up motorbikes
‘Loses’ vehicles when they're moving at your speed

The obvious comparison to the Gardia R300L would be the Garmin Varia system, and for quite a lot less money the Bryton does an impressive job of detecting cars from an impressive distance away. The beam is pretty good too. 

There are also some bonus extras, like the easy-to-use smartphone app and smart light capabilities. The unit pairs with most head units (not just Bryton) and Bryton says it can detect vehicles up to 150m away. Our reviewer found it could pick up from even further away than that, about 180-200m on long, straight roads. 

As a light it is also very effective, with five settings and just a quick press to flick between them. The light also detects changes in speed and can deploy a brake light, and a flashing light pattern that changes when a car is approaching to increase the chances of you being seen.

There are some small quirks like patchy pick-up of motorbikes and losing vehicles when they're moving at your speed, but overall this is a decent light and radar system in one. 

Magicshine SeeMee 300 Smart Tail Light

Magicshine SeeMee 300 Smart Tail Light

8
Buy now for £39.99 from Bike Inn
Downward-pointing OptiTracing light gives added illumination
Good run-times
Mount fits all shapes of seatpost
Light sensor isn't very reactive

While not as super bright as the name might lead you to believe, the Magicshine SeeMee 300 is cleverly designed and has a lot going for it, all without being very expensive. 

The smart mode allows the sensor on the light to monitor ambient lighting levels and adjust the light's brightness accordingly - it's optional, and there are also low, high, flash and group ride modes if you'd prefer to set it manually. The Smart Mode really is quite smart, flashing 300 lumens during the day and switching to a 100/20-lumen flash plus the OptiTracing light on a static 60 lumens. 

The mount should fit all seatposts, and our reviewer used it in all weathers and found this light very rugged and weatherproof. 

Best rear bike lights: how to choose and what you need to know

faq-icon
Should rear bike lights be flashing?

In terms of the law, it's up to you. The law requires flashing modes to be between 1Hz and 4Hz (one to four flashes per second) but actual modes vary considerably and some fall well outside that. Pulsing constant modes are a grey area.

Ask a rider why they have their light flashing and they'll often argue that it makes them visible from further away. Ask another rider why they have a constant light and you'll often hear that it makes distance easier to judge for following vehicles.

There's not a lot of scientific research to hang your choice on. Most people who run two lights will have one of them flashing. One thing to bear in mind is that if you're riding in a close group – be that a club run, sportive, Audax or anything else – having a bright light flashing in your eyes at close range is pretty annoying. Many lights have low-power steady modes for group riding.

faq-icon
Are bike lights a legal requirement?

In the United Kingdom, it is a legal requirement for bikes to have a white front light and a red rear light illuminated when ridden on public roads during the hours of darkness. 

In terms of the law, it's up to you whether your rear light is flashing or not. 

faq-icon
What is the recommended lumens for a rear bike light?

A rear bike light doesn't need to be as powerful as a front light as its primary aim is for you to be seen rather than to see. 

A rear bike light of between 50-100 lumens is sufficient but it depends on the type of riding that you plan to be doing.

If you're mostly just pootling to the shops and back then something basic will probably do the job. Simple flashers that use button cells or AAA batteries are cheap and effective these days, and they last ages before the battery needs replacing.

If your commute is on busier roads, or you plan to do longer rides at night, you'll probably want something brighter. There's a wealth of USB-rechargeable and brighter AAA-powered rear lights about that will catch a driver's attention from further afield. Many riders who spend a lot of time on the road after dark fit more than one rear light to increase their chances of being seen.

faq-icon
How long do bike light batteries last/how long before I need to recharge?

This can vary massively and depends on whether the rear bike like is rechargeable or battery-powered. 

Most rear lights will cope easily with the longest ride you're likely to throw at them, though not all USB-rechargeable ones can be fully trusted to last a whole night, especially on steady beam. If you're planning some big forays into the dark unknown – or if you're just a bit crap at remembering to charge your lights – pick something that has a long run time. AAA-powered lights tend to be the pick for that.

A lot of rechargeable lights will have some sort of system for warning you if you're about to run out of juice. Multiple lights we've tested have a small green light to indicate they're full or close to fully charged, moving to amber and finally red to tell you the charge is low. 

When it comes to rechargeable lights, beware of the highest advertised run times vs mode. Flashing modes will usually last much longer than steady settings, simply because less light is being omitted overall. As an example, the Giant Recon TL 200 recommended in this guide has a max advertised run time of ten hours on its smart night mode, but this goes down to 2.5 hours on the 100 lumen high setting. Let's say you have a one hour commute each way, and you prefer to use the higher setting, that means you really need to be charging the light every night. A mid-setting will probably be best for most commutes though, so if your journey is half an hour or less each way you could get at least a week's worth of use out of most mid-range rechargeable lights. 

faq-icon
Where is the best place to put the rear light on a bike?

The best place to mount a rear light on a bike is typically on the seatpost or seat tube, facing directly backwards as this provides a clear and unobstructed view of the light from behind. Some bike lights will also fit under the saddle. 

Depending on your bike's design, you might also consider additional mounts such as a rear rack or saddlebag, providing alternative locations for mounting lights.

The article states "A rear bike light of between 50-100 lumens is sufficient but it depends on the type of riding that you plan to be doing." Yet you give the 20 lumen Knog Plus Rear Light the Cheapest road.cc-recommended rear light award! 
If you just want cheap and not really functional light (20 lumens IMO is not suitable for riding on the road in traffic, barely better than a glow worm) then there are planty of other similar spec but cheaper lights on eBay and Aliexpress (or Aldi as someone has suggested).
A 20 lumen light might be suitable as a spare emergency backup in case your main 50 lumen plus light dies or goes flat, but that's about it.

Surprised this didn't get a mention for side lights: https://orb.bike/product/the-orb-mkii/

I use mine all winter on my commute, although I don't usually drink much/anything. I've got the old, original version and wouldn't think twice about buying another if I lost mine or it broke.

Once I started using it, it made me really aware how much I may or may not be seen from the side in different situations.

It comes with my big rubber stamp of approval - but I'd like to see road.cc review it and hear their thoughts.

A fine idea. I've put Christmas lights in a water bottle, and seen some very good YouTubes of people placing very bright LED lightstrips and big batteries in bottles which were very cool.
But of course this gets use of the bottle too.
If the manufacturers would send the product to road.cc for proper testing...

You invest a modest amount in one of the many available adaptors or (more fun) you make a bodge yourself, a short length of appropriately-sized pipe, a drill/Dremel and some cable ties usually does the trick for me.

I have a rack pack, and commute using panniers.
The rear light mount of my rack has a reduced section in the middle ... so it starts wide then narrows and then goes back to wide.
I found out that the centres of the mounting holes on the rack mount are too far apart for anything I had laying around; but, the narrow bit was the right width to fit between the bolts of a seat rail mount.
Because of the shape of the rack mount, the seat rail mount can't go anywhere - there is too little space between the centres to allow side to side movement, and the shape of the rack mount doesn't allow for up and down movement.

A few extra pennies (less than 20quid) and an aluminium tee action cam mount later, and both my Garmin radar and my Fly6 Gen 3 are securely mounted with very little movement.

I share your pain. Bontrager Flare RT is the remedy. I use their rear mudguard mount, but they also make a variety of other mounts, including a seat stay mount. Bonus is that the light can switch on/off with your Garmin, saving the hassle when the light itself is mounted out of reach from the saddle.

I use a handlebar extender on the side of the seatpost to gvie me 2" of extra width. They usually cover up to 32mm diameter tubes, so will do either the small tube attached to the seat or the larger seat tube.

Cost £5 to £10, and need to be installed such that they touch neither your heel nor your thigh.

No option for me as the under seat saddlebag is full of batteries for the Gruber Assist.

The availability of good quality mounts is one of the reasons I like Cateye. Although the parts are sold separately, they cover various seatpost sizes (SP-6 covers 26-30mm IIRC), clothing clip* and a pannier rack mount.

I have been using a Viz 100 for a few months now and I am impressed enough to buy a second one for my dry/summer bike (it's currently just £15 in Halfrauds). Brighter than I expected with impressive wide angle visibility. The Viz 300 and 450 models are OTT, quite unnecessary.

The Lezyne strap for my 800XL front light snapped the other week, it broke near the end, the bit I have to pull around the handlebar. £14 and the LBS will have to order it. A design weakness, it will surely fail without warning again in the future.

* it used to be included with some models so I have 3 or 4 of these.

In contrast, I have been using the simple stretchy rubber straps on my Aldi lights for 5 years now and none of them have torn yet. They're what I use to film apparently non-existent vehicles like Y40 DAN. The significance is that the vehicle was initially identified and reported as 'No MOT' in July 23. I have come across these disappearing vehicles around here before

Not so sure about the 300 and 450 being unnecessary.

I've been on a few NSL roads with low, very bright sun directly in front of me. I was confident that the 300 would show up and less confident that other models would. (also it will do 30 lumens in other modes).

Was also very glad of my radar too !

I'm normally commuting with a Carradice saddlebag, so can't use seatpost-mounted lights as they're obscured. It would be useful in your reviews if you mentioned whether lights come with either a seatstay mount (eg most Cygolite taillights have both seatpost and seatstay mounts in the box) or a belt clip that will fit the mounting strap on saddlebags.

I use a NiteRider Sabre clipped onto the back of my rucksack. It has a big clip, never had any retention problems. In fact use it there so much I'm not sure where the actual mounting bracket is!

The Knog+ ('lightest rear light') has a decent looking clip. The actual bracket for it works with magnets and gets good reviews.

I am considering the Knog Blinder Link, the saddle rail version. As a bit of an extra, and to lower my Hope District+, as I can with my mudguards.

I did want something to go on the right hand seat stay, a Moon, but the weatherproofing seemed somewhat inadequate, and I was unsure of the fixings.

The Knog has a USB C, which will mean I need another cable as this will be the first for my lights...

I'm using the Knog Blinder on my pannier and it works great so far. The USB C charging is however terribly slow. The attachment clip might look cheap but is easy to attach/remove and the light is hold tighly in place. Using it for about 1 year now, almost every day, would definitely buy again.

Thanks for that, impressive range of brackets, but nothing that does it for me. The Flare has a seatstay bracket, but I would prefer a cob striplight there. The seat lights seem to be wired for ebikes and dynamos, the knog looked very cool, but the quick attachment seemed weak for such an expensive unit, I'd considered Exposures little rear as an underseat light, better bracket and lots of printed aftermarket ones too, but then difficulties for removal when leaving and when needing to charge.
It's for an extra extra light, so not essential, which is why I'm after "perfection", already have the Hope R4+ on the seatpost, an Exposure RedEye piggybacking my Axis on the helmet and a NiteRider Solas 250 as a baglight.

the Cateye Viz is frustrating me. It comes with a plastic mount that you slide the light into, then you wrap a rubber block over the mount, which stops the light from sliding out. Then you use the rubber "ladder" to hold the light to the seat post.

Two problems I've found:

  1. to get the light off the bike to charge it, you have to take the whole thing off your bike, to be able to slide the light out of the mount
  2. if you use the light horizontally, the tag at the end of the rubber "ladder" has to be forceable bent and squashed between the light and the mount - leaves me worried it isn't actually seated properly and will fall off

Not following the second point - the ladder end locking is independent of the orientation.

The image on the left is how you have to have the rubber block to slide the light in and out, the the part you slide the light out of is how it is held onto the seat post - so you would have to pull it away from the seat post and push the rubber back (as i have in the photo) and then slide the light out.

The image on the right is the light put in horizontally - the tag is pushed out by the light and makes me worried it'll slip out of the mount.

I see what you mean now - I have one of those but use it on a Brompton with the proprietary Brompton seat mount, which allows it to slide in and out easily. I've just dug out the original mount like yours and it's just as you say. One solution for off-bike charging perhaps would be to get an alternative mount? The Cateye square mount is fairly common and there should be others available.

I wasn't envisaging you making it horizontal on the seat post, I thought you were using it elsewhere as horizontal.

I've just tried and you can slot the light on afterwards if you want horizontal and the retaining tab in the square mount will hold it. I needed an allen key to move the tab to get the light out.

Hmm, although I don't use that mount any more and I'm now wondering if I've lost a bit !

EDIT

Apologies, I have found the missing bit and now I understand the issue. What is even more bizarre is the site shows the horizontal placement as an option with no reference how it is very hard to get it on.

USB-C is now a must, when will we see more manufacturers implementing this... 

But why I hear you cry.. 

1) No right or wrong way up so no bent connections

2) Higher amp bandwidth means faster charging

3) future proof (until the next better thing sticks at least)

Amen. At this point it's a no-brainer. It would be helpful if the charging port could be in the first line of the review, could save a lot of wasted reading!

USB C is a bit of a mixed bag, sometimes it means what you say, like higher charging current and quicker charging times but all too often USB C charging protocols aren't observed so none of those benefits are actually available, and in many cases a compliant USB C charger won't charge your light at all. The USB C plug is certainly better than micro usb though.
