ABSTRACT:
A lamp having a minimum number of parts consisting of lamp terminals, a lens, light bulb and reflector, the lens and reflector forming a sealed envelope containing the light bulb, the bulb lead wires being secured directly to the inner ends of the terminals positioned within the envelope and constituting a light source assembly. The terminals extend through openings formed at the rear of the reflector, the openings being large enough to allow adjustment of the light source assembly with respect to the reflector in the X-Y-Z axes by manipulating the light source assembly from the rear of and outside the lamp envelope thus simultaneously compensating for variations between bulbs, reflectors and lenses. The lamp is aimed simultaneously with adjustment of said light source assembly. The defined construction eliminates the need for mounting and sealing ferrules and separate lead-in wires between the terminals and the bulb.
