Light module for a motor vehicle

A lighting device for a motor vehicle, comprising:

• a main light module for generating at least part of a low beam or a high beam, wherein the main light module has a first light source, a primary optic, and a secondary optic, and wherein the main light module is configured such that light emitted by the first light source passes through the primary optic and the secondary optic;
• a signal light module for generating at least one signal light function, wherein the signal light module has a second light source, a flat light guide with an entry surface and an exit surface, and an optical component, wherein the optical component is an optical disk or an optical film, wherein the signal light module is configured such that light emitted by the second light source enters the entry surface, emerges from the exit surface, and passes at least partially through the optical component or is reflected by the optical component;
• and
• an additional optical component, the additional optical component being an an optical disk or an optical film that has an entry surface and an exit surface, wherein a structure is provided on the entry surface or the exit surface of the additional optical component, and wherein the additional optical component is arranged in the lighting device such that, during operation of the lighting device, light generated by the main light module and light generated by the signal light module propagates through the additional optical component.
