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.
