Abstract
A headlight has a light source and a reflector. A screening device is associated with the light source and has a web located at both sides of the light source and extending along the optical axis. A light-impermeable cap forms a part of the screening device arranged under the light source. A gap-like opening remains between the upper edges and the lower edges of the webs. Above the web, light emitted by the light source and reflected from the upper region of the reflector can pass and form a low beam to produce an upper bright-dark limit by the upper edges of the webs. The light passing through the gap-like openings is reflected from the lower region of the reflector and forms an additional light beam arranged at a distance above the bright-dark limit.
