Abstract: An exterior luminaire for a motor vehicle includes a number of light sources and one or more fiber bundles, each including a number of flexible light-guiding fibers. The exterior luminaire is configured such that, during operation, light originating from the light sources is fed into the fiber bundle(s), as a result of which a respective fiber bundle emits light along its length, the light passing at least partly via a light-transmissive covering sheet into the exterior of the motor vehicle. In the exterior luminaire, a respective fiber bundle is accommodated at least in sections in the longitudinal direction in one or more grooves, a respective groove including at least two joined-together holding components, which form the contour of the respective groove in cross section and which hold the respective fiber bundle by interlocking engagement and/or force-locking engagement.

Abstract: A motor vehicle includes a radiator grille and a lighting apparatus with a number of light sources. During operation, the lighting apparatus emits light, which originates from the number of light sources, from the radiator grille into the surrounds of the motor vehicle. The lighting apparatus includes a number of flexible fiber bundles. Each fiber contains one or more fibers and has a homogeneous outer surface for generating homogeneous light radiation in a circumferential direction of the fiber bundle. Further, each fiber bundle is arranged at least in sections on the radiator grille and coupled to at least one light source at at least one light one fiber bundle end, the light source feeding into the at least one fiber bundle end during operation.
