Carnegie Mellon University industrial design students Jonathan Ota and Ethan Frier developed the Aura system that brings attention to bicyclists by lighting up their bike. The students incorporated six groups of three tri-colored LEDs attached to the rims of a bike. The lights are powered by a generator built into the front hub.
