Abstract
The headlight has a light source (10) in the form of a gas discharge lamp and a reflector (12) which has a first reflector part (16) and a second reflector part (18). A converging light beam is reflected from the first reflector part (16) and a lens (26) and a stop (22) with an edge (24) for producing a light-dark boundary are arranged in the path of that beam. The second reflector part (18) is arranged above and/or beside the first reflector part (16) and is moveable between a position for low beam light, in which a light beam directed downward is reflected from it, and a position for high beam light, in which a light beam with a greater range is reflected from it. The light reflected by the second reflector part (18) in the position for low beam light can issue from the headlight and contribute to the formation of the low beam or be absorbed inside the headlight. A completely effective high beam is formed by a combination of the light reflected from the second reflector part (18) with the light reflected from the first reflector part (16) in the operating configuration for the high beam light.
