Smart LEDs Increase Bicycle Visibility And Driver Awareness At Night
Project Aura uses RGB LEDs installed inside bike rims to tell drivers the speed of an oncoming bike. By increasing overall bicycle visibility, the creators hope to decrease the number of collisions.
Project Aura, started by Ethan Frier and Jonathan Ota, addresses the safety issues of many urban cyclists when commuting at night. RGB LEDs are embedded in the front and back rims of the bike, powered by a front hub dynamo.
The LEDs change color from red at slow speeds to white at cruising speed. They also cover a greater surface area and illuminate brighter than the standard attachable lights. This makes it easier for drivers to ‘search, detect and evaluate’ situations involving cyclists.
