This tail light mounts to your seat post or seat stays and gives you wide-angle visibility up to 260°. A solid mounting system won't let go, even on bone-shaking off-road rides.
Up to 50 hours of unblinking run time when used with two high-capacity AA batteries. A quick snap adapter makes the light easy to attach and remove, while the flat design fits easily into your pocket.
Forgetful? The IX-Red Senso LED Tail Light (note Senso in the name) is basically the same light, but it turns itself on and off when needed.
