The One23 Super Bright 0.5 rear light is just that. By my reckoning (not to mention singed retinas of those behind me), its good to eight hundred and fifty metres in flashing - and the lens profile ensures 180 degree visibility.
The price is the real shocker. Only a few years back this sort of performance would set you back thirty odd quid. Here you'll get change from a tenner at many online retailers - batteries included!
Measuring 6x4x3cm, it's nice and minimalist and coupled with a super stretchy rubberised bracket can be helmet mounted. A fairly compliant clothing clip clings to jersey pockets, bag loops and shoulder straps.
Accessing the AAA cells means separating the casing via a coin slot with a 2p or 5p. Transparent battery tray aside, there's little to see, or touch for that matter, which explains why it has survived a five minute hosepipe test and immersion in twenty-five centimetres of seawater.
There are three LEDs, with three settings - steady, flash and hybrid where the main stays constant while the others dance their socks off. A recessed, top mounted switch is pretty discreet and requires a two second press to engage, so unwanted start-ups should be highly unlikely.
Out in the sticks and helmet mounted this light is visible from a good 750 metres and the side visibility has saved my bacon when emerging from secluded driveways. Through town, strobing is at just the right tempo not to get drowned out but once again, it is most effective at eye level.
A seriously bright rear light for a seriously small amount of money

Tell us some more about the technical aspects of the light?
1/2 watt LED

Extremely well sealed from the elements, although plastic proved a little softer than premium brands around the battery slot.
Very simple and ladder type strap will even stretch to accomodate helmets.
Passed hosepipe torture testing and North sea immersion with flying colours.
Managed 92 hours in flashing, 49 constant, which is pretty frugal coming from two AAA cells.
Switch could prove tricky to operate wearing really thick winter gloves.
Tell us how the light performed overall when used for its designed purpose
One23 super bright 0.5 watt rear LED is phenomenally bright and will give some household names a seriously good run for your money. Maximum visibility is nearer 850 rather than 1000 metres in flashing modes,450 constant/peripherally.
Mounting hardware entertains the full zodiac of seatpost diameters and is very accomodating of modern helmets/luggage too. However, trailers/tag alongs will need two on account of modest surface area.
