A vehicle headlamp assembly is provided which includes a light bulb providing a source of illumination; a reflector housing with a central opening with a reflector surface for reflecting illumination given by the light bulb, the reflector housing central opening mounting the light bulb, the reflector housing having a first surface opposite the reflector surface adjacent the central opening and a second surface on the same side of the reflector surface generally adjacent the central opening; and a bulb shield having a first portion along a first end. The first portion is generally closely adjacent to the light bulb for blocking illumination provided by the light bulb. The bulb shield has at an end opposite the first end at least one foot penetrating through the central opening with a radially outwardly extending toe engaging the reflector housing first surface. The bulb shield also has a coil spring contacting the reflector second surface urging the first end of the bulb shield away from the first and second surfaces of the reflector housing.

Headlamp assembly with coil spring bulb shield

An automotive vehicle headlamp assembly is provided which includes a reflector housing having an open front end, a first reflector surface and a second surface projecting forward from the first reflector surface; a bulb connected to the housing projecting forward from the reflector surface providing a source of illumination; a lens covering the open end of the reflector housing; and a bulb shield having a first portion generally adjacent the bulb, blocking a portion of the illumination given off by the bulb. The bulb shield has a foot connected by a leg to the first portion. The foot has a front end captured between the lens and the reflector housing and a rear end captured in the intersection between the first and second reflector surfaces.

Headlamp assembly with hook-in bulb shield

An arrangement of an aimable vehicle headlamp assembly is provided which includes a bulb; a reflector housing mounting the bulb; at least one rod with a balled end mounted to the vehicle and extending therefrom, the balled end having first and second sides; a first sleeve housing encircling the rod having an open end for receipt of the first side of the rod balled end; a second sleeve housing connected to the housing with an open end for receipt of the second side of the rod balled end; and a flange connected to one of the sleeve housings for receipt into a groove in the sleeve housing the flange is not connected to. Pivotal connection of the reflector housing to the rod is achieved by insertion of one of the sleeve housings into the other sleeve housing and torquing one of the sleeve housings, and placing the flange in one of the sleeve housings within the groove of the other sleeve housing.

Quick release vehicle headlamp arrangement

An arrangement of an aimable vehicle headlamp assembly connected to a panel of an automotive vehicle is provided including in a preferred embodiment a bulb; a reflector housing mounting the bulb; at least one rod connecting to the panel of the vehicle and projecting therefrom with a balled end; a longitudinal channel connected to the reflector housing facing the panel of the vehicle, the channel having a forward wall having a depression, and the channel having side walls with converging flange portions spaced from the forward wall with a slotted region between the flanges; and a slider with a top tab, the slider being slidably mounted in the channel and captured by the forward wall, side walls and flanges, the slider having an elongated aperture having a first diameter larger than the rod ball and a second diameter smaller than the rod ball wherein to connect the reflector housing to the panel of the vehicle, the ball of the rod being generally aligned with the channel depression through the slot region in the channel, and thereafter the slider is moved downward.

A vehicle headlamp assembly having a retainer of a replaceable light bulb assembly that includes three circumferentially spaced sections each independently attached to the rear of the reflector and located around the opening which receives the light bulb of the light bulb assembly.

Headlamp assembly

A vehicle headlamp assembly having a lamp unit supported by three ball pivots each of which is connected to the reflector member of the lamp unit through a pair of socket portions which encapsulate the ball portion of the associated ball pivot and are connected together by a fastener accessible from above the headlamp assembly and which, when removed, allows the lamp unit to be released from the vehicle.

A ventilation system for a replaceable bulb headlamp in which the reflector member is formed with at least two slots in line with and behind the sealant channel and each slot is adapted to slidingly receive a vent device which establishes a labyrinth-type flow path for air to enter and exit from the interior of the headlamp.
