Abstract: A system for illuminating a wheel on a vehicle, the wheel having a concave area adapted for mounting around a wheel hub attached to stationary structure on the vehicle, the vehicle having an electrical power source. The system includes a contact ring that includes a circular backing ring of an electrically insulating material and a layer of electrically conductive material over the backing ring. The contact ring is flexibly supported from the concave area of the wheel where a contact brush mounted from the stationary structure of the vehicle makes contact with the layer of electrically conductive material on the contact ring. At least one electrical light emitting device is electrically connected to the layer of electrically conductive material on the contact ring, so that electrical power from the power source reaches the light emitting device through the contact brush and through the contact ring.
