Holy crap, is this not the cutest tail light ever? It’s 75% more cute than the previous cuteness champion, . Very clever design. The little tail stays mounted, and you unscrew the light to recharge it. It’s bright, not wicked insane bright, but bright enough that all but the folks who used to be school crossing guards will think it’s plenty bright. 20 hours on a charge. Solid only, and other flashy flashy options, but we say only use that solid mode!  

Mounts to any rack or fender braze on. Don’t be an idiot and mount it down by your axle. Mount it on your seat stay upper rack mounts. So it’s visible. Putting it by the axle might look cool, but as your mom used to say: you can’t look cool if you are dead. Unless you are zombie James Dean. Maybe then you can do both.

Machined aluminum. Do 3 things when mounting: smear beeswax on the bolt threads that your going to use to mount the light to the frame. Sandwich the light mount between two And wax the threads on the light nubbin’. The wax is like a basic loctite.
