Big Cobber produces an incredible 330º of light, so you'll be clearly seen from all angles. In an increasingly busy world, this bike light is brilliantly effective at attracting attention and helping keep you safe on the road. Packing 470 lumens up front and 270 lumens in the rear, these Big Cobbers are seriously bright. The Cobber has integrated USB recharging, is 100% waterproof and you can program the settings using Knog's Modemaker software.
