13. A headlight lens for a vehicle headlight having a light source, the headlight lens including

a lens body made of a transparent material, which includes an essentially flat surface and an essentially convex surface; and

an emblem, situated on the essentially flat surface, having a basal surface, which, with respect to the essentially flat surface or with respect to an optical axis of the headlight lens, is sloped in such a way that light entering into the lens body through the essentially convex surface parallel to the optical axis of the headlight lens is subject to a total reflection at the basal surface, or

which, with respect to the essentially flat surface, is sloped at an angle between 25° and 50° or, with respect to an optical axis of the headlight lens, is sloped at an angle between 30° and 55°.

14. The headlight lens as recited in claim 13 , wherein the basal surface is offset by between 0.2 mm and 6 mm with respect to the essentially flat surface.

15. The headlight lens as recited in claim 13 , wherein the emblem extends in a relief-like manner beyond a part of the essentially flat surface or of the essentially convex surface or is situated in a recess in the lens body.

16. The headlight lens as recited in claim 15 , wherein the emblem extends in a relief-like manner beyond a bottom surface of the recess.

17. The headlight lens as recited in claim 13 , wherein a projection of the basal surface onto the essentially flat surface covers less than 30% of the essentially flat surface or a projection of the basal surface onto the essentially convex surface covers less than 30% of the essentially convex surface.

18. The headlight lens as recited in claim 13 , wherein the essentially flat surface or the essentially convex surface includes:

a region having a roughness of at least 0.05 μm.

19. A vehicle headlight, the vehicle headlight including:

a light source;

a lens made of a transparent material, which includes a surface facing the light source and a surface facing away from the light source; and

an emblem, situated on the surface facing the light source, having a basal surface,

which, with respect to an optical axis of the headlight lens, is sloped in such a way that light entering into the lens body through the surface facing away from the light source parallel to the optical axis of the headlight lens is subject to a total reflection at the basal surface, or

which, with respect to the surface facing the light source, is sloped at an angle between 25° and 80° or, with respect to an optical axis of the headlight lens, is sloped at an angle between 30° and 55°.
