These brilliant Bike Ball lights naturally bob-around while you ride, boosting your visibility. They light up your rear so drivers can see you and your balls, providing some laughs as well ensuring your safety.
Built for rough riding - water/splash resistant construction.
Gently squeeze Bike Balls to turn the light on and switch between the solid/flashing modes. Gently squeeze again to turn the Bike Balls off. They come with batteries included. These can easily be replaced.
A mounting loop effortlessly attaches on the back of your bike seat (or backpack, tent, stroller, almost anything!) See images for a graphic demonstration.
These make an excellent gift for a ballsy bike rider.
