ABSTRACT:
A skate has a wheel rotatably mounted on an axle with a light emitting element mounted on the wheel for making the wheel illuminative when an electrical potential is applied to the light emitting element. The electrical potential can be supplied by a battery installed within the wheel through a switch which can be actuated by rotating a cap movably mounted on the hub of the wheel or contacts actuated by centrifugal force upon rotation of the wheel. The rotor and stator of an electrical generator can be mounted on the axle and wheel to generate the electrical potential in an embodiment which does not require a battery.
