Abstract

The invention relates to a headlamp lens for a vehicle headlamp, wherein the headlamp lens comprises a precision-molded body made of a transparent material, wherein the body comprises at least one light tunnel (108) and a light-conducting part (109) with at least one optically active light exit surface (102). The light tunnel (108) comprises at least one light entry surface (101) and merges with a bend (107) in the light-conducting part to depict the sharp bend as a light/dark boundary by means of light coupled or radiated into the light entry surface. The surface of the light tunnel (108) is at least partially convexly curved in the region of the bend (107).
