Abstract
A sealed beam lamp assembly, suitable for use as a motor vehicle headlight, has an incandescent lamp mounted within an inert-gas-filled, molded-glass housing integrally comprising a reflector and a control-lens cover. For supporting the lamp in position within the housing, a metal-made support rod extends forwardly from one of ferrules on the reflector and has its front end preformed into the shape of a U to provide a rearwardly directed fold. Welded to this fold of the support rod is a metal band rigidly encircling the base of the lamp. The lamp position relative to the reflector is therefore adjustable as required by manually turning the fold of the support rod about its main straight portion. The support rod serves also to provide electrical connection between the ferrule and one of the lamp leads.
