Abstract

A headlight for a vehicle has a reflector, a light source, a lens through which a light reflected by the reflector passes, and at least one element which surrounds the lens at least over a part of its periphery and is at least partially light permeable so that the light emitted by the light source and not engaged by the reflector passes through the element and is collected, the element being provided with ring-shaped optical profiles which form a Fresnel lens.
