Cruzin Brightz red, blue, and green lights create a spectrum of colors to bring the party to your bike. Easily attach it to your handlebars and project patterns on the pavement. No tools are needed to allow for easy installation and removal. The light even separates from the clamp, so you don't have to reinstall everything later. Compact size allows for quick and easy storage in a purse or backpack. Run on 3 AA batteries (not included) for 20+ hours of party lights.
