Abstract

A vehicle headlamp comprising first second light sources and first and second lens. Each lens comprising a precision-molded, one-piece, element of a transparent material. Each one-piece element comprising a light tunnel and a light-conducting part having an optically effective light exit surface. The first lens light tunnel comprises an optically effective, light inlet surface and transitions into a light-conducting part while making a first bend for imaging the first bend as a light-shadow line by means of light coupled in or irradiated onto the light inlet surface. The second lens light tunnel comprises a second optically active, light inlet surface and transitions into a second light-conducting part while making a second bend for imaging the second bend by means of light coupled in or irradiated onto the light inlet surface, the second bend (substantially) being a variant of the first bend mirrored on a straight line.
