Abstract

The disclosure relates to a vehicle headlight (20), for example a motor vehicle headlight, wherein the vehicle headlight comprises a light source assembly (11) and a primary optics (200A), for example a press-molded primary optics, for example a one-piece primary optics (200A), wherein the primary optics (200A) comprises at least one light tunnel (208) and a wedge-shaped light conducting part (209) having at least one light exit surface (209A), for example optically effective light exit surface (209A), wherein the light tunnel (208) comprises at least one light entrance surface (201), for example an optically effective light entrance surface (201), into which light generated by means of the light source assembly (11) can be irradiated, wherein the light tunnel (208) transitions into the light conducting part (209) at a bend (207), and wherein the vehicle headlight comprises a secondary optics (200B) with an optically effective light exit surface (202) for imaging a light exit surface (209A) of the primary optics (200A) and/or of the light conducting part (209) or for imaging the bend (207).
