Night riding will be safer with REVOLIGHTS

Revolights uses rings of LEDs attached to your bicycle wheels to replace the common headlight.

The LEDs shine white light on the forward wheel and red light on the back. A magnet tracks speed and orientation to control the lights. The LEDs zip around the entire tire when stationary, making your bike hard to miss at night, whether you're rolling or not.

Revolights are bright enough to light up your path while also screaming, "Bicycle!" to any car approaching from your side.

The first batch of Revolights are designed for 700 series road and hybrid rims. A battery charge will get you through four hours of riding time.

Pledge $200 on Kickstarter and you'll get a set of Revolights with an anticipated delivery date of March 2012. The final retail price is expected to be $220.
