Abstract

A light-guide element for a lighting device for a motor vehicle, wherein the light-guide element has a defined position for a light-emitting diode, a first reflection surface, a second reflection surface, and an outcoupling surface. The defined position, the first reflection surface, the second reflection surface, and the output coupling surface are arranged relative to one another such that light from the light-emitting diode is emitted from the defined position in a first light direction to the first reflection surface, is reflected at the first reflection surface to the second reflection surface in a second light direction substantially opposite to the first light direction and can be deflected from the second reflection surface onto the outcoupling surface in a third light direction.
