Exposure Flare Mk 2 Rear Light

Review from road.cc

The Flare is the self-sufficient rear light from Exposure, a development from their Red-Eye rear light that sucks power via a lead out the back of one of Exposure's powerful Joystick off-road lights. The tidy little Flare runs off a single CR123A battery - a squat camera battery to you and me. It pushes out a bright 75 lumens of red light via a Seoul P4 LED. Exposure say there's 9hrs of constant light to be had with a disposable battery and 3hrs with rechargeables, or 22hrs and 8hrs respectively in flashing mode.

The Flare is pretty much moulded in to its moulded bracket so it's never going to bounce out and the whole combo is so small and neat that they really don't need to come apart anyway. The seatpost bracket is also angled so the light points horizontally when mounted, although it can be flipped so the Flare points slightly down, which handy if you ride in a group and don't want to blind the rider behind. The bracket's silicone band will stretch to fit seatposts from 25.0-34.9mm and, because of the shape of the bracket and flexibility of the band, will also wrap round odd-shaped aero seatposts and seatmasts too. This stretchy attachment makes it easy to swap the light between bikes or to remove it for security when commuting.

This Flare has been switched between road, cyclo-cross and mountain bikes with a variety of seat-tube sizes, without recourse to screwdrivers or faffy shims, and that silicone band has kept it securely attached to every seatpost it's been on. The little light's been vibrated along stuttery tarmac and bounced off-road and it hasn't wobbled or made a launch for freedom into the verge.

Turning the Flare on and off is a matter of simply twisting the lens clockwise or anti-clockwise. To change the mode from constant to flashing, or vice-versa, is just as easily done by turning the Flare off and on again within three seconds. Otherwise, it turns on in the same mode as when it was turned off. The one-handed on/off operation, turning the whole lens, means there's no fumbling about trying to press fiddly power buttons with thick winter gloves on. With a bit of practice, the light can be operated on the move, should stopping ruin your PB. Indeed the fact that bracket and light are effectively one-piece is another advantage when it comes to on the move operation because the light doesn't swivelin it's bracket when you are trying to twist the lens something it's front light equivalent, the Flash, does.

The flashing mode isn't an on/off flash. The light is on constantly with the flash pulsing over the top. It makes the Flare a powerful visibility aid, even in daylight, and is great for peace of mind in the city or riding the lanes into the sun. The lens is diffused and about 1cm deep so there's a certain amount of traffic-useful side visibility there as well.

The Flare's PR trick is to be dropped into a pint of beer and to stay working until people get bored, or someone wants their beer back. It's a stunt that works in the real world too. All very entertaining of course a more real world test would be to fire beer at it in all directions in the way rain and spray is forced against a bike light on a stormy day. You might get asked to leave the pub though.

So how does its weather sealing stand up to real world conditions? I kept the Flare on the back of my bikes all winter, even when it wasn't dark, just to get it covered in as much road grime and puddle splash as possible. It's refused to roll over and die. .

With no on/off buttons to press, a traditional weak point with lights for moisture to enter, and an O-ring seal between the lens and the CNC aluminium body, water and anything else that might be flung up by the rear wheel or fall from the skies has a hard time getting in. As a result, the Flare hasn't faltered due to internal dampness and hasn't had to be put in the airing cupboard to dry out. Dave and Tony have also put a winter and more's commuting time in to the Flare with no problems on that score either

Battery life has been hard to gauge against Exposure's claimed figures as it's been used in a real-world random configuration of flashing and constant modes. But the supplied battery is lasting well, definitely on a par with other proper battery lights, and markedly better than those that use dinky watch-style batteries.

On the road, the Flare is an impressively bright 75 lumens, so bright that the spotlight burst of red actually casts a wide pool of light over the rear wheel and onto the road, further contributing to visibility. Its first ride out was on pitch black country roads and it was instantly apparent that cars were showing more respect, hanging back and taking a wide overtaking arc rather than the usual forcing past without hesitation. It inspires a plucky confidence to shadowy riding. Riding behind a pair of night time cyclists, one with an Exposure Flare and one with what was once considered a decent enough blinky light, revealed how much brighte

In conclusion...

Well made, compact, confidence-inspiringly bright, impervious to weather, and easily swapped between bikes
