ABSTRACT:
A long useful life, light permeable cover of pigmented, injection-molded silicone rubber for elastic manual placement over and self-retention on a light source enclosure. The cover, due to memory, is self-biasing and self-retaining upon the light source enclosure against inadvertent removal and may be used in large multicolor, automatically programmable, electrically changeable, broad spectrum displays, such as scoreboards.
