Abstract

A headlight for a motor vehicle having a light source, a reflector having a substantially concavely curved reflection surface by which a light emitted by the light source is reflected for producing a predetermined illumination intensity distribution, the reflector having at least one further reflection surface which follows the concave reflection surface in a light outlet direction, a light-permeable member located in a beam path of the light reflected by the reflector and formed so that the light passes through the light-permeable member without being substantially influenced, the at least one further reflection surface of the reflector being subdivided at least locally by visible separating lines into several facets, at least a part of the facets being formed so that the light emitted by the light source is reflected by the at least one part of the facets into at least one lateral region in front of the vehicle.
