Abstract: A unitary assembly for a headlight and other lights at the front of a vehicle, particularly a large truck, has an integral housing with mountings for the headlight and other lights at each side of the vehicle's front. The housing is secured at the back side of the vehicle's front skirt or other front surface, positioned so that the headlamp is aimed through an opening provided in the front surface of the vehicle. The housing also provides a mounting for the turn signal light, positioned below the headlight, and preferably also for a side marker light and a reflector. In a preferred embodiment, the unitary assembly at one side of the vehicle includes an air inlet in the portion of the housing immediately surrounding the headlamp. The air inlet is for taking in air for the interior of the cab or for an air conditioner or heater.
