Abstract
Abstract This invention relates to polymer sealed beam headlamp units and more particularly to a mounting assembly for securing these headlamp units to vehicles. The assembly includes a headlamp having a plurality of mounting blocks integral with and mediately articulated from the reflector portion of the lamp envelope. The mounting blocks project outwardly from the exterior surface of the envelope and reference the lamp beam through the envelope reflector. The mounting blocks have openings for receiving and engaging fasteners therein for securing the headlamp to a vehicle. The fasteners are inserted in the blocks and adjusted relative thereto to referentially relate the lamp alignment to the vehicle. The fasteners are resiliently biased by buggy springs which at least partially surround the fastener. The non-attached head of the fastener is inserted within a slotted vehicle panel and is tensionally secured thereto by the buggy springs. Although a preferred mounting employs three mounting blocks, one of the mountings can be pivotal and non adjustable. Adjustment of the fasteners aligns the headlamp relative to the vehicle. The headlamp in one embodiment is provide with a decorative trim rim about the face of the envelope.
