The invention relates to an electric lamp, provided with a metal-plastic cap, for a motor vehicle headlight, which has a pressing-on spring (100) which is arranged laterally on the lamp cap and serves to mount the lamp in the reflector opening, constructed as lamp holder, of the headlight. The lamp cap has a metal holder part for the lamp bulb, a metal annular carrier sleeve (14b) connected thereto, and a plastic cap part (15) in which the carrier sleeve (14b) is anchored. According to the invention, the annular carrier sleeve (14b) has two inwardly angled lugs (14d) between which the pressing-on spring (100) is arranged with a clamping fit, and which are crossed with the ends (104a) of the pressing-on spring (100).
