Abstract
The invention is an electroluminescent dome light for a convertible vehicle. The lighting element consists of a thin piece of electrically conductive material, which is specially treated with an electroluminescent coating. The element is enclosed in a phosphorous treated laminate which provides structure and diffuses the light emitted, giving it qualities of incandescent light. Two electrical connectors attach to the element to provide a means for generating an electrical current though the conductive material. The lighting element is held in place on the headliner of the convertible by a housing, with a means of attachment.
