ABSTRACT:
A reflector (3) of a motor vehicle headlight is coupled with a housing (1) by an adjustment device (4) with which it is pivoted about an axis (10). The adjustment device substantially comprises an adjusting pin (12) rotatably mounted in an opening in the housing with an end portion thereof extending outwardly from the housing opening, forming a hand knob (23) thereon for rotating the pin. An indicating device of the motor-vehicle headlight substantially comprises a toothed gear (20) with a scale-like indicator thereon and a pinion gear (16) which is formed on the hand-knob portion of the adjusting threaded pin. The toothed gear is mounted on an axle (25) extending outwardly from the housing and rotates freely in a position in which it interengages with the pinion gear. The toothed gear lies flatly on an outer surface (17) of the housing. The toothed gear has a central opening (24) and an off-center opening (27) adjacent the central opening. The openings (24, 27) are in communication with one another through a stricture ( 28) which is narrower than a cross section of the axle and of which, at least on one side, is radially flexible because of an adjacent cavity (30) in the toothed gear. Thus, the toothed gear can be moved between a first position in which the toothed gear interengages with the pinion and in a second position in which it is removed from this interengagement.
