Abstract: A roller skate wheel having a conical cavity includes an insert housing arranged for complementary reception within the cavity. The housing includes a housing base plate, with the base plate including a socket to receive the wheel fastening axle structure therewithin. A transparent forward plate is mounted in a spaced, parallel relationship relative to the base plate. A plurality of illumination bulbs diametrically aligned within the housing adjacent the forward plate are in electrical communication with a battery housing mounted medially of the housing, and wherein the battery and battery housing include first electrical contact support legs resiliently mounted, with the first electrical contacts mounted to distal ends of the legs for engagement with further electrical contact legs directed into the illumination bulbs, whereupon centrifugal force in use of the roller skate wheel completes electrical circuitry to effect illumination of the bulbs within the housing.
