Check out this great new idea for bicycle wheel lights that increase visibility and also light up the road for the bicyclist. It seems very helpful for side visibility compared with the standard front and rear lights.

In Wisconsin, the law requires bicycle operators during hours of darkness to have a white front lamp visible from 500 feet and a red rear reflector at least two inches in surface area visible between 50 and 500 feet when under lawful upper beams form a car. What are hours of darkness? What if the red reflector is visible from 25 feet but not 495? Are upper beams the same as brights?
