ABSTRACT:
The headlight has a light source (12) which is mounted in a main reflector (10) by which a convergent light beam is reflected, which passes through a lens (16). An additional reflector (22) is arranged surrounding the main reflector (10) between the main reflector (10) and the lens (16), by which light not captured by the main reflector (10) is reflected as an additional light beam with horizontal scattering. The light beam passing through the lens (16) forms a low beam, by which a predetermined low beam light distribution is provided with an upper light-dark boundary. The additional light beam produces an additional uniform light distribution, which overlaps the low-beam light distribution. The headlight illuminates a larger surface than the surface of the lens (16) because of the additional reflector (22) surrounding the main reflector (10) and the lens (16) so that it causes no glare or blinding. The headlight can have a cover disk with a smooth surface without optical elements and thus a uniform appearance.
