At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
If you just want to be seen or you want a set of emergency lights, then you can't get much more reasonably priced than the KranX Sabre 85 USB Twinset. They chuck out a decent amount of illumination, will cope with some rain and shouldn't turn on accidentally in your bag, and while they aren't perfect, you really can't really complain for this sort of money.
For a light to be seen by 85 lumens offers a decent amount of punch, and when using either of the two flashing modes you should hopefully get picked out by drivers among the background of a dreary urban environment. And if you are in the market for bike lights – front and rear, to see and be seen by – have a look at our best bike lights buyer's guide.
In the box you'll find two lights: one front, one rear. These are basically identical to each other although – with the obvious exception that one is white and the other red.
They are operated via a button on the side/top depending on the light's orientation. You press and hold this button to turn it off or on, while a quick press lets you scroll through the four modes – two solid, two flashing. Because of their design both lights offer good visibility from the sides too.
Battery life ranges from three hours to 14.5 hours, which I easily achieved in practice, and they only take a couple of hours to charge through a USB input hidden behind a rubber cover. This helps to give the Sabre lights their IPX4 rating, which means they can resist water being sprayed at it rather than a biblical deluge.
That said, I used the rear light on a seatpost on a bike without mudguards and even on wet days water ingress wasn't a problem.
Their mounts are simple rubber straps that screw into the rear section of each light. It simply wraps around the seatpost or bar with whichever hole in the strap lines up with the hook on the opposing end. This makes fitting and removing them quick – ideal if you have to leave your bike unattended.
The mounts are tapered, which works brilliantly on the rear light as the seatpost angle ensures the light sits vertically.
The problem is that the front has the same mount – so when you fit it to your handlebar it doesn't point straight ahead. It points to one side or the other, which I found really irritating. Even at this price, a separate mount for the front light shouldn't have been too difficult to include.
That said, as they cost just £24.99 the pair I'm not going to complain too much. Yes, you can pick up lights for a fiver in a bargain supermarket, but you won't be getting 85 lumens, and they'll probably be running coin batteries that will work out more expensive in the long run.
Not perfect, mostly down to that front mounting strap but you're getting a high output and decent build quality for very little money.
Well-priced lightset considering the output, although the front mounting point is irritating

Tell us what you particularly disliked about the lights
The front mount means the light doesn't face directly straight when it's mounted on the handlebar.
How does the price compare to that of similar products in the market, including ones recently tested on road.cc?
They are well priced, coming in much less than competitors mentioned in the review, and those also offer less output.

Would you consider buying the lights? Yes, although I'd modify the front mount.

The front mount could do with a tweak, but apart from that the Sabres are a well-built set of lights that chuck out plenty of illumination for the money.

As part of the Tech Hub here at F-At Digital, our senior product reviewer Stu uses the knowledge gained from putting well over a 1,000 products through their paces (including hundreds of bikes) to write in-depth reviews of a huge range of kit. After first throwing his leg over a race bike back in 2000, Stu's ridden more than 160,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him he still likes to smash the pedals rather than take things easy. Although, as he spends a fair bit of his time reviewing ebikes these days he's becoming an expert in letting the motor take the strain. He's also waiting for 23mm race tyres to make a comeback!
