1. A motor vehicle lighting module comprising:
a housing which is formed by a housing part and a circular or elliptical outer part attached to the housing part, wherein the outer part is at least partially translucent and closes off the housing to an outside,
a plurality of light sources that emit light beams, wherein the light sources are accommodated in the housing, and
a light guide system arranged in the housing, into which the light sources emit the light beams, wherein:
a facet body comprising an upper part, a girdle and a lower part is arranged in the housing, wherein the upper part adjoins the outer part and the lower part projects in a direction of the housing part,
the light guide system comprises a first light guide and a second light guide, wherein the first light guide comprises a disk-shaped section, wherein the girdle of the facet body lies in a central recess of the disk-shaped section, and wherein the second light guide is configured as a conical, curved body, the curvature of which runs around an underside of the facet body,
the light sources are arranged such that the light sources feed light into the first light guide and into the second light guide,
a first portion of light emitted from the disk-shaped section of the first light guide is introduced into a side of the girdle,
a second portion of light emitted from the disk-shaped section of the first light guide is introduced into the outer part, and
a third portion of light emitted from the second light guide is introduced into the lower part of the facet body.
