The light source is allocated to the first light guide element, and the first light guide element has a first light in-coupling region and a first light out-coupling surface, the second light guide element has a second light in-coupling surface and a second light out-coupling surface, with the first light out-coupling surface facing the second light in-coupling surface. A light distribution structure is provided on at least a partial segment of at least one of the first light out-coupling surface and the second light in-coupling surface. The vehicle lamp includes the optical assembly described above.

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.

Multiple light sources are arranged in an array. A light guide member receives light emitted from the multiple light sources on its back face, and outputs the light thus received from its front face. The light guide member has a base portion such that its back face faces the multiple light sources and such that it extends in the array direction of the multiple light sources. Multiple back-face protrusions and multiple front-face protrusions are formed such that they protrude from the back face and the front face of the base portion. The front-face protrusion has multiple continuous faces in the circumferential direction along the front face of the base portion.
