Abstract
A headlight for a vehicle comprises a reflector. A light source having a light body. A shutter forming an upper bright-dark limit of a light bundle exiting the headlight. A lens arranged after the shutter is considered in a light outlet direction so that light reflected by the reflector passes through the lens. The reflector being formed so that light produced by the light body is reflected by the reflector so that it intersects an optical axis of the reflector and from the apex region of the reflector great images of the light body are reflected so that after passing through the lens they are arranged substantially close to the bright-dark limit. The reflector having a shape which is determined so that a distance along the optical axis between an apex point of the reflector on the optical axis and intersecting points of light rays reflected by the reflector with the optical axis starting from the apex region of the reflector to an edge region facing the apex region in the light outlet direction is changeable so that after passing through the lens at least approximately all images of the light body are arranged substantially close to the bright-dark limit.
