Fibre Flare's Single Tail rear light is a truly ground breaking, iconic lighting system that holds its own in pretty much any context. It uses fibre optic technology, a huge visible surface area and 'wand' shape that puts its visibility. You can see it from 425 metres in the sticks, dipping to 300 through rush hour traffic.
However, while it seems very likely to prevent sorry-mate-I-didn't-see-you hits, it is defined as a portable safety device, so pair it with a regular back light, especially if you've hung it on a rucksack or messenger bag to prevent an otherwise negligent driver wriggling away on a technicality.
Available in a range of colours and several lengths, it's consists of a phenomenally strong, flexible solid core with two high power LEDs, which are in turn, amplified by fibre optic components for captivating effect. It's powered by AAA batteries, a more practical choice for Audax and touring contexts as yo can get replacements anywhere, although the Single Tail's robust weather seals make roadside replacements a little fiddly.
The Fibre Flare Single Tail passed my hosepipe test and laughed at wet coastal roads despite being hung horizontally on a low-slung touring trailer. Its silicone 'ladder' straps wrap round tubing diameters between 10 and 60mm. If you don't like clutter, they're easily trimmed.
The shape and attachments straps open up plenty of possibilities for creative illumination. With a Fibre Flare down each seat stay and an extra light on my wedge pack I was able to mimic the highly visibly light layout of a contemporary French car.
Laying a Fibre Flare horizontally along my trailer's top rails was similarly effective and eliminated moments of going stealth when turning right or entering traffic flow. Of its two modes, flashing has been my default and is distinctive enough to avoid being lost among competing light sources .
The steady mode is hardly impotent but consumes juice at nearly twice the rate, though the run times are pretty frugal at 28-33 hours in steady mode against 62-68 hours in flash, depending on cell type and quality.
The switch is positive enough that you're unlikely to turn it on or off accidentally, but it's a faff if you're wearing winter weight gloves.
Superb light system for anyone but better than most for tandems and similarly specialist configurations.
