Abstract

A headlight for vehicles with a projection module is provided, which includes a bowl-shaped reflector, an illumination unit dedicated to the reflector, a lens, and a shutter arranged between the lens and the reflector. The shutter forms a light-dark-border of a light bundle. The lens features a convex front side facing away from the reflector and an optical element mounted to the headlight in the lower middle margin area on the front. The light beams emerging from the optical element are directed to an area above the light-dark-border of the light bundle of the headlight. In vertical second planar sections, to which the optical axis of the projection module extends perpendicularly, the surface of the optical element is concave-shaped, and in vertical planar sections extending parallel to the optical axis, it is convex-shaped.
