  • the second surface area is provided according to the invention as an exit area for the light. It is arranged, for example, at a position of the trim part not directly visible to the vehicle occupant in order to create the impression of a backlighting of the trim part, for example in an edge region of the visible side.
  • the second surface area may, for example, be slit-shaped.
  • the light-emitting means is preferably at least one substantially punctiform light source, in particular a light-emitting diode. It is particularly easy to equip the trim part according to the invention with a light emitting diode.
  • a vehicle with, for example, unlit fairing part, can be equipped by inserting the light-emitting diode in the inventively provided recording very easy to retrofit.

  • the trim part 10 has a first surface area 1, which according to the invention is designed so that the light is controlled in the interior of the trim part 10. At least a majority of the light rays do not penetrate through the first surface region 1, but are reflected by it. This can be achieved by covering the surface with an opaque material is covered, for example, a decor, such as a foil or a paint. According to the invention, it is provided that the first surface region 1 can have geometric shapes, such as prisms, so that a high proportion of the light rays is reflected at the surface due to an acute angle of incidence. Likewise, the first surface area 1 may be roughened.
