Abstract

The headlamp arrangement has one or more light sources, at least one reflector and a lens (1). The optically active, i.e. directly illuminated lens diameter is extended by an edge region (2a) that is not optically active or not directly illuminated by focus light. The edge region is in the form of an annular element applied or attached to the lens.
