Motion powered bike wheel lights.

Two industrial design students at Carnegie Mellon University, Pittsburgh, Pennsylvania, USA, have created a new bicycle saftey system that uses the bike’s movement to light the wheels. Ethan Frier and Jonathan Ota have a created a system which lights the wheels white while the bike is in motion, and red if it detects the bike is slowing down.

They have blogged their whole project on tumblr at with photos and videos.  A trailer of what there have created is below:
