Abstract
An assembly for the merchandizing of products utilizing a solar cell mounted directly onto an incandescent or florescent light bulb so that the cell receives the light directly from the light bulb. A d.c. motor is electrically and physically connected to the solar cell, the motor shaft extending downwardly. A substantially planar sign member having word indicia formed thereon is operatively interconnected to the motor shaft so that it rotates in response to motor shaft rotation. The interconnection preferably is provided by a piece of metal foil extending vertically and attached to the motor shaft, and a slip swivel connector between the metal foil and the sign member which allows some slippage between the foil and the sign member so that the sign member rotates more slowly than the foil--slow enough for appropriate normal recognition of the word indicia thereon. A plurality of flexible clips may be provided for mounting the solar cell directly to the light bulb, or globe for the light bulb. Alternatively, a fan blade may be mounted to the motor shaft.
