Abstract
An apparatus for illuminating rotating wheels on vehicles includes a stepper motor mounted on the rotating wheel, a counterweight mounted on the shaft of the stepper motor, and a plastic tube mounted on the wheel for rotation therewith containing a plurality of light emitting diodes interconnected with a wire attached to the stepper motor. Rotation of the wheel causes the stepper motor body to turn relative to the counterweighted shaft thereby producing electrical pulses sufficient to illuminate the light emitting diodes.
