Illuminate your night rides with these exciting, super-bright, multi-colored spoke lights! The kit includes three light sources (red, green, and blue) attached to plastic tubing that can be clipped onto the spokes of the wheels in an unlimited combination of patterns to produce a wide variety of different lighting effects. Clip straight down the spokes, or make spirals and loops to switch up your mobile light show. No charging or accessories required; 2 CR1220 batteries for each light source will provide over 24 hours of continuous light.
NOTE: Each light source requires 2 CR1220 batteries (6 total for full operation) - 6 batteries are included to get you started!
