1. A light-guide element for a lighting device for a motor vehicle, the light-guide element comprising:
a defined position for a light-emitting diode;
a first reflection surface;
a second reflection surface; and
an outcoupling surface,
wherein the defined position, the first reflection surface, the second reflection surface, and the outcoupling surface are arranged 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 that is substantially opposite to the first light direction, and is deflected from the second reflection surface onto the outcoupling surface in a third light direction,
wherein the outcoupling surface is arranged at an angle to the second reflection surface in a range between 90° inclusive and 170° inclusive, and
wherein a holographic element and/or optical scattering element are arranged or formed on the outcoupling surface.
