Abstract
Abstract In a lighting fixture such as an exit sign, a mounting base assembly is provided on a light emitting diode lighting device for mating engagement with an electrical socket. Once full mating engagement is achieved between the electrical socket and a base member of the mounting base assembly, the position of the housing carrying the light emitting diodes of the lighting device can be adjusted for alignment purposes without disturbing the full mating engagement of the electrical socket and the base member.
