Abstract
A headlight for a vehicle operating in accordance with the projection principle, the headlight has a reflector, a light source, a lens through which a light reflected by the reflector passes, at least one partially light-permeable element which surrounds the lens at least over a part of its periphery, so that light which is emitted by the light source and not engaged by the reflector passes through and is collected by the at least one element, wherein, the reflector and the lens being formed so that light which is reflected by the reflector and passes through the lens forms an upper bright-dark limit, the element being formed at least locally as a fresnel lens with ring-shaped optical profiles, and further optical profiles arranged at least in a part of a beam path of the light passing through the element and deviating the light so that it illuminates a region in front of the vehicle above the bright-dark limit formed by the light reflected by the reflector and passing through the lens.
