Abstract

A headlight for motor vehicles has a reflector, a lamp support, a gas discharge lamp arranged in the reflector on the lamp support and including a region extending in the reflector and a glass cylinder which at least partially absorbs light in UV-wavelength range and surrounds the region of the gas discharge lamp, and a light stop which at least partially screens a light emitted by the gas discharge lamp. The light stop is at least indirectly mounted on the reflector, the glass cylinder is held on the light stop at least in its end region facing a light direction, the glass cylinder adjoins the lamp support, and the lamp support and the gas cylinder are arranged so that an opening leading to an interior of the glass cylinder remains between the lamp support and the glass cylinder.
