Abstract

A headlight system is provided for a motor vehicle and includes, but is not limited to at least one light source and beam-forming apparatus for generating the main light beam with an essentially horizontal cut-off line and a marker light beam within a limited azimuth angle range above the cut-off line of the main light beam. The beam-forming apparatus are switchable between at least two stationary states that differ from each other in the progression of an upper cut-off line of the marker light beam.
