Abstract

A headlight for a vehicle has a light source, a reflector reflecting light emitted by the light source as a light bundle converging at least in horizontal longitudinal planes, the reflector having a front edge facing in a light outlet direction, and a dispersing lens arranged in the region of the front edge of the reflector so that the light bundle reflected by the reflector passes through the dispersing lens, the reflector and the dispersing lens having shapes which are such and so determined relative to one another that the light emitted by the light source after reflection on the reflector and passage through the dispersing lens forms a light intensity distribution sufficient for requirements corresponding to regulations.
