Zusammenfassung: | A headlight for a vehicle operating in a projection principle has a light source, a reflector reflecting a light emitted by the light source, a lens arranged in a course of light reflected by the reflector, a first shade device located between the reflector and the lens and changeable between at least one first condition for a first operational position of the headlight and at least one second condition for a second operational position of the headlight, the first shade device in the first condition screening a part of the light reflected by the reflector and producing a bright-dark limit of a light bundle exiting the headlight, and in the second condition screening at least only a smaller part of a light reflected by the reflector than in the first condition, and a further shade device arranged in a direction of an optical axis offset relative to the first shade device and changeable between at least one first condition and at least one second condition, the further shade device in the first condition screening a part of a light reflected by the reflector and passing on the first shade device in the first condition so as to reduce a maximum illumination intensity value produced by a light bundle exiting the headlight in the first operational position, the further shade device in the second condition screening at least only a smaller part of a light reflected by the reflector. |
