Abstract

A vehicle headlight, especially a supplementary headlight, comprises an H1 type lamp (21), a collar member (18) of a heat-resisting plastics material moulded directly around the base (22a) of the lamp, and a reflector (16) of a thermoplastic material moulded around the collar member. The complete headlight is replaced when the lamp reaches the end of its life. <IMAGE>
