Abstract: The headlight has a reflector which is mounted inside a casing for swiveling about a swivel axis extending approximately in a horizontal center plane of the reflector, close to the apex region of the latter. The front edge, pointing in the light emission direction, of the reflector has an at least approximately circular arc shape in planes at right angles to the swivel axis and the center point thereof is arranged at least approximately on the swivel axis. The casing has a part whose edge pointing opposite to the light emission direction adjoins the front edge of the reflector and, in planes at right angles to the swivel axis, likewise has an at least approximately circular arc shape, and whose center point is arranged at least approximately on the swivel axis. Because of this design the gap between the casing part edge and the front edge of the reflector can be kept small, since when the reflector makes a swiveling movement about the swivel axis, the gap varies only slightly or not at all.

Abstract: The headlight has a reflector mounted inside a casing and swivelable about an axis by an adjustment element rotatably mounted in the casing. The adjustment element has a portion formed eccentrically to its axis of rotation. In the casing a transmission element is mounted for swiveling about an axis and is swivelably connected to the reflector. The transmission element has a recess in which the eccentric portion of the adjustment element is received, so that the transmission element is coupled, in the tangential direction relative to the axis about which it is swivelable in the casing, to the eccentric portion. On rotation of the adjustment element the reflector is swiveled about the swivel axis and the magnitude of the swiveling movement of the reflector is determined by the magnitude of the eccentricity of the portion and the lever ratios of the transmission element.
