Abstract: A shock absorbing lamp assembly for baseless cartridge bulbs for on and off the road motor vehicles, including a rear backing lamp housing member serving as a reflector and lamp housing, a lens cover joined about its perimeter to the housing member to cover said cavity, an elongated baseless cartridge lamp bulb in the cavity having a larger central bulb portion housing filament wire and opposite generally flattened bulb end portions hermetically sealing about filament support pins to support the internal and external portions of the filament support pins, bulb mount assembly comprising a semi-circular U-shaped mounting plate carried on swaged anchor formations of the housing member and a pair of forwardly projecting vertically and laterally flexible shock absorbing arms extending parallel to each other generally perpendicular to the axis of the bulb from the mounting plate formed of rubber-like material of about 60 durometer hardness and having terminal receiving apertures for receiving the flattened bulb end

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.

Abstract: The reflector mounting member of a lamp is provided with a receptacle formation in which the lamp bulb base is seated and retainer formations in which a pair of connector devices are seated. One or two insulated conductor cables are inserted into the connector devices to thereby pierce the insulation and establish electrical connections through the connector devices to the bulb filaments.
