Abstract

The headlight for a motor vehicle has with an electromotive adjusting device (5) for adjusting a reflector (2). The adjusting device (5) includes an electric motor (7) and a step-down gear unit which are accommodated in a housing part (12) which is arranged within the headlight housing (1). The step-down gear unit includes a small worm gear (8) and a large toothed wheel (9) with radial teeth. A rotational movement of the toothed wheel (9) is transformed via a thread between the toothed wheel (9) and the housing part (12) into a movement of the toothed wheel (9) along an axis (6) determining the adjusting direction. The toothed wheel (9) is connected with the reflector (2) via an articulated part (18). The housing part (12) is supported in the headlight housing (1) so as to be rotatable. A basic adjustment of the reflector (2) is possible from outside the headlight housing (1) via an adjusting part (26) acting on the housing part (12) by means of rotating the housing part (12).
