Abstract
A headlight for a motor vehicle comprises a gas discharge lamp as a light source emitting visible light and light in UV-wavelength region, a reflector having a first region which reflects the light for forming a low beam and a second region which reflects an additional light beam illuminating a region located beyond a region illuminated by the high beam, a filter arranged in a path of the additional light beam and at least partially absorbing the visible light and at least partially permeable for light in UV-wavelength region. The filter is formed by a coating which covers the second reflector region and is composed of a filtering material.
