An automotive headlight with a bowl-shaped plastic reflector. The reflector has at its apex an opening surrounded at the rear of the reflector by a sheet-metal retaining ring. The ring accommodates an incandescent lamp. The lamp is inserted into openings in the reflector with its securing tabs bent back toward the reflector and is secured to the reflector by barbs on the securing tabs that engage the edges of the holes. To improve the headlight to the extent that the openings in the reflector that accommodate the securing tabs are large enough not to shorten the life of the tool and do not need to be produced with such a precise tolerance, while still ensuring that the retaining ring will fit the reflector reliably and snugly, the securing tabs are bent into a U and the openings in the reflector that accommodate the tabs are quadrilateral and approximately as high and as wide as the tabs.
