WHEELBRIGHTZ RAZZLE DAZZLE

It's glow time! 20 micro LED lights create a ring of brilliant color that will grab attention wherever you go. Easy riders will freak over the cool hues while grownups will see bike safety in a whole new light. 7' of tubing can be cut to size and works with most wheels 20" or larger, and is intended for one wheel. Requires 3 AA batteries, not included.
 

From Brightz, for ages 8 yrs-teen.
