    Abstract: An automatic headlamp-aiming system for a motor vehicle wherein a headlamp is hingedly connected to the vehicle for controlled rotation about a horizontal axis as driven by a vacuum motor which is energized upon operator initiation of an aiming cycle. Control means including a single-ended mercury switch electrically connected to a solenoid serves to automatically deenergize the vacuum motor and lock the system against further movement when the headlamp attains a properly vertically aimed position.

    Abstract: A rearview mirror assembly for a motor vehicle wherein a mirror element is provided with a nontransmissive, electrically conductive reflective coating across the exterior viewing surface. Elongated contacts extending along the top and bottom edges of the coating provide a uniform current path across the coating when an electrical potential is applied thereacross to directly resistance heat the coating. The low-thermal conductivity of the mirror element acts as an insulating barrier which serves to retain heat at the coating, thereby improving the thermal efficiency of the assembly. A backing plate, adhesively attached the other surface of the mirror element, mounts the mirror element on a ball stud located within the cavity of a mirror support housing on the exterior of the vehicle, thereby permitting adjustable universal movement of the mirror element about the ball stud within confines of the cavity. A manual control switch is provided for selectively applying heating current to the coating.

    Abstract: A motor vehicle headlamp wherein a projection lamp, universally adjustably connected to a motor vehicle by a unitary hinge, has a rearward aiming and seating plane which, when positioned in a known plane relative to the vehicle, will project a light beam in a desired horizontal and vertical illumination pattern. An aiming block formed on the hinge and referenced to the aiming plane cooperates with an aiming string connected between headlamps on opposite sides of the vehicle to visually indicate when the lamp is properly horizontally oriented. A liquid level referenced to the aiming plane visually indicates when the lamp is properly vertically oriented.
