Ideal for the frequent commuter, The Radiant 750 Rechargeable Bike Light is 750 lumens and provides 180° of bright white illumination to see and be seen, day or night. It features high, low, and attention-getting day-safe flash modes, and is easily recharged via USB. It attaches to handlebars with a unique tool-free wristwatch-style handlebar mount that allows the light to slide on and off a bike to be used independently or for security purposes.
