Vehicle headlight including:
- a first light source;
- a headlight lens comprising a monolithic body of transparent material, the monolithic body including:
- a light passage section including a optically operative light exit face;
- and
- a light tunnel comprising a light entry face, wherein the light tunnel passes over, via a bend, into the light passage section for imaging the bend as a light-dark-boundary by means of light irradiated from the first light source into the light entry face;
- and
- at least a second light source spatially separated from the first light source, the second light source being configured for irradiating light directly into the light passage section without passing through the light tunnel.
