Good lighting was important because I often rode through fog. After a few years, I concluded that the best equipment was the stuff that required the least input and no maintenance. That meant reflective attire. This week I discovered Project Aura, a system from my home state of Pennsylvania, that increases visual footprint of cyclists--especially near intersections. It works because of rotational surface areas. Light comes from RGB LEDs inside the rims of the wheels that change from red when slowing down to white when at cruising speed. The whole rig is self-powered by a dynamo. It deserves a look.
