An illuminated wheel includes a power source made up of series-connected pairs of parallel-connected button type batteries or parallel-connected pairs of series-connected batteries, a printed circuit board on which are mounted arc shaped common contacts for the circumferential outer electrodes of each pair of batteries and individual contacts having resilient arms for engaging the planar contacts of the batteries while accommodating battery thickness variations, an integrated circuit controller for controlling the duration and timing by which power is supplied to a plurality of lighting elements, and a motion sensitive switch made up of a pair of contacts extending from the circuit board and a conductive plate having two openings loosely fitted over the respective contacts of the contact pair. The circuit bard is positioned in a recess molded into the wheel, and the recess is closed by a transparent or partially transparent snap-on cover which exhibits optical effects such as diffraction or magnification of light from the lighting elements.
