Don't let the lack of daylight limit your opportunity to explore. With Bookman's Clip-On Reflector, it's never been safer to take a midnight ride. Strong magnets make it easy for you to clip the reflector onto your bike frame, your shirt, or even your helmet. The reflection lets cars know where you are, and the slim design won't slow you down or add any unnecessary weight. Ideal for night-biking, this simple reflector works equally well for running in the moonlight or 2 AM dog walks.
