Abstract

A headlight for a vehicle has a holder, at least one reflector displaceably supported on the holder, an adjusting device for displacing the reflector and including an adjusting screw having a thread and a displaceably guided transmission element which is articulately connected with the reflector and with the adjusting screw so that during turning of the adjusting screw the transmission element is displaced in a longitudinal direction to displace reflector. The transmission element disengages from the thread of the adjusting screw in the longitudinal direction after the transmission element has reached a predetermined maximum longitudinal displacement, but after a smaller displacement it abutts against at least one abutment, so that during a further movement of the transmission element until the transmission element disengages from the thread of the adjusting screw, a return force is produced which loads the transmission element in an opposite longitudinal displacement direction.
