Abstract
A generally planar base panel member has mounted to its back face a pair of laterally spaced apart chambers whose open fronts are covered by the panel. A pair of electrical receptacles in each chamber are arranged in alignment with apertures in the base panel. First and second front panels each have a neon tubing configuration mounted on a front side of the panel with the electric end terminals at opposite ends of the tubing configurations projecting through holes in the front panels so that when the front panels are juxtaposed to the front of the base panel the neon tube terminals plug into the receptacles. A power supply for neon tubing is mounted to the back face of the base panel member. The neon tubing configurations on the individual front panels when plugged into the receptacles form a series circuit which connects across the high voltage output terminals of the power supply.
