ABSTRACT:
A single filament dual function shock mounted or conventional vehicle signal lamp assembly adapted to be connected to vehicle safety light signalling circuits to serve tail and stop/turn lamp functions and the like, comprising a unitary molded rear backing housing member serving as a reflector and a lamp housing and a lens cover member sealed about its perimeter to the housing member and enclosing a single filament lamp bulb which may be shock mounted within the cavity of the housing. A generally flat annular electronic circuit board in the form of an interrupted ring shaped to encircle the housing cavity is mounted inwardly adjacent the lens cover at the perimeter of the cavity and includes a pair of unidirectionally conductive diodes and an elongated resistor element rigidly mounted on the circuit board to couple the lamp bulb to vehicle control circuits to serve tail and turn/stop signal functions.
