Claims19
Vehicle headlight including:
- a first light source;
- at least a second light source;
- a first headlight lens comprising a first monolithic body of transparent material, the first monolithic body including:
- a first light passage section including a first optically operative light exit face;
- and
- a first light tunnel comprising a first light entry face, wherein the first light tunnel passes over, via a first bend, into the first light passage section for imaging the first bend as a light-dark-boundary by means of light irradiated from the first light source into the first light entry face of the first headlight lens;
- and
- at least a second headlight lens comprising a second monolithic body of transparent material, the second monolithic body including:
- a second light passage section including a second optically operative light exit face;
- a second light tunnel comprising a second light entry face, wherein the second light tunnel passes over, via a second bend, into the second light passage section for imaging the second bend as a light-dark-boundary by means of light irradiated from the second light source into the second light entry face of the second headlight lens, wherein the second headlight lens comprises an optical axis which is inclined with respect to an optical axis of the first headlight lens by at least 0.5°;
- and
- further comprising:
- an additional light source for irradiating light directly into the first light passage section.
