Abstract
The invention relates to an electric lamp, provided with a metal-plastic cap, for a motor vehicle headlight. In order to prevent maladjustment of the lamp, caused by the formation of burrs on the reflector (20), during installation in the mounting opening (21), designed as a lampholder, of the reflector (20), the lamp cap (14b) is fitted with depressions (14f) or cutouts so that any possible burr (22a2) on the edge (22a) of the mounting opening (21) is arranged free from contact with the lamp cap (14b, 15).
