Abstract
A headlight for a vehicle has a reflector, a light source, a collecting lens arranged after the reflector in a light outlet direction so that light emitted by the light source is reflected as a converging light beam and the light beam exiting the headlight has an upper bright-dark limit, the reflector being formed so that images of the light source reflected by the reflector are located in an intermediate image plane which is perpendicular to an optical axis of the reflector in the region of a focal point of the collecting lens facing the reflector and above an imaginary line corresponding to a height and side running of the bright-dark limit.
