Abstract

A headlight for a vehicle operating in accordance with a projection principle has a reflector, a light source, a lens through which a light emitted by the light source and reflected by the reflector passes, at least partially light-permeable element which at least partially surrounds the lens at least over a part of its periphery and is provided locally with optical profiles so that the light emitted by the light source and not engaged by the reflector passes through the element and is collected by the element, the light reflected by the reflector and passing through the lens forming an upper bright-dark limit, and at least one additional light source which produces a limiting light and is arranged so that the light emitted by the at least additional light source at least partially passes through the element.
