Abstract

A lighting device for a motor vehicle, having at least one light guide, which is formed planar, and having at least one illuminant. Light rays from the illuminant can be coupled or are coupled into the light guide via a light incoupling surface assigned to the light guide. Incoupled light rays are deflected via at least one light outcoupling structure of the light guide in the direction of at least one light outcoupling surface of the light guide and are again outcoupled from the light guide via the light outcoupling surface. The invention proposes that a rear surface of the light guide, which surface is opposite to the light outcoupling surface, is provided at least over a majority of its planar extent with a facet-like surface structure, which forms the light outcoupling structure of the light guide and formed of a plurality of irregularly formed facet surfaces.
