1. An exterior luminaire for a motor vehicle, the exterior luminaire comprising:
a plurality of light sources; and
one or more fiber bundles, each of which comprises a plurality of flexible light-conducting fibers, wherein:
the exterior luminaire is configured such that, during operation, light originating from the plurality of light sources is fed into the one or more fiber bundles, as a result of which a respective fiber bundle emits light along its length, the light passing at least partially via a light-transmissive cover lens into an exterior space of the motor vehicle,
the respective fiber bundle is accommodated at least in sections in a longitudinal direction in one or more grooves, wherein a respective groove includes at least two joined-together holding components by which a contour of the respective groove in cross section is formed and which hold the respective fiber bundle by at least one of interlocking engagement or force-locking engagement,
the cover lens comprises a region in which, for at least one groove, the cover lens engages around the associated at least two joined-together holding components and presses the associated at least two joined-together holding components against one another by exerting an elastic force, and
in the region of the cover lens, engagement sections are provided on the cover lens, the engagement sections engaging in corresponding engagement sections of the at least two joined-together holding components.
