Knog 12142 flashlight bike mount IP67, Black/Red

The Knog+ (pronounced "plus") rear bike light is a super-bright, 100% waterproof and totally versatile USB rechargeable bicycle light. Mount the light to your seatpost, seat stays and pannier racks, or use the integrated wearable clip to attach the light to your t-shirt or backpack. More of a runner than a cyclist? No dramas. The Plus light also doubles up as a wearable night running light. Just attach the light to your tshirt, shorts, socks or headband using the smart integrated clip. With an output of 20 lumens and a run time of up to 40 hours in eco flash, the Plus ensures you are well seen to all other cyclists, road users and trail runners all night long.
