The Knog+ (pronounced "plus") bike light is a super-bright, 100% waterproof and totally versatile USB rechargeable bicycle light. Mount the light to your bike, 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 t-shirt, shorts, socks or headband using the smart integrated clip. With an output of 40 lumens(Front) 20 lumens(rear) and a run time of up to 20 hours(Front) and 40 hours(Rear) in eco-flash, the Plus ensures you are well seen to all other cyclists, road users, and trail runners all night long.
