1. An illumination apparatus for a motor vehicle, the illumination apparatus comprising:
a lighting device which has one or more light sources,
a reflector arrangement which has one or more scattering reflectors, and
one or more transparent bodies, each of which has a surface made up of a plurality of planar facets,
wherein the illumination apparatus is configured such that light which is generated by the one or more light sources of the lighting device is scattered on the one or more scattering reflectors of the reflector arrangement, resulting in scattered light which is at least partially refracted at a first facet of the one or more transparent bodies upon entering the one or more transparent bodies, is subsequently reflected by at least one second facet of the one or more transparent bodies, and subsequently exits from the illumination apparatus to generate a light distribution, and
wherein at least one scattering reflector of the one or more scattering reflectors comprises a plurality of irregularly arranged reflection elements.
