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?
(1) No person may operate a bicycle, motor bicycle, or electric personal assistive mobility device upon a highway, sidewalk, bicycle lane, or bicycle way during hours of darkness unless the bicycle, motor bicycle, or electric personal assistive mobility device is equipped with or, with respect to a bicycle or motor bicycle, the operator is wearing, a lamp emitting a white light visible from a distance of at least 500 feet to the front of the bicycle, motor bicycle, or electric personal assistive mobility device. A bicycle, motor bicycle, or electric personal assistive mobility device shall also be equipped with a red reflector that has a diameter of at least 2 inches of surface area or, with respect to an electric personal assistive mobility device, that is a strip of reflective tape that has at least 2 square inches of surface area, on the rear so mounted and maintained as to be visible from all distances from 50 to 500 feet to the rear when directly in front of lawful upper beams of headlamps on a motor vehicle. A lamp emitting a red or flashing amber light visible from a distance of 500 feet to the rear may be used in addition to but not in lieu of the red reflector.
