  • First region 3 is a first group of first light sources 1 attached, in the second region 4, a second group of second light sources 2 is attached.
  • the light sources of both groups are light emitting diodes (LEDs).
  • the first group comprises a total of 16 light-emitting diodes, one of which is arranged centrally in the middle of the pane of the area 3 and five or 10 further light-emitting diodes surround this central light-emitting diode concentrically.
  • the LEDs 2 of the second group comprise a total of 20 LEDs, which are arranged equidistantly on the annulus of the area 4 of the board 11 so that they surround the light emitting diodes 1 of the first group concentric.

  • the control unit can control the light-emitting diodes 1 and 2 so that they shine differently bright. In particular, at least two brightnesses can be controlled.
  • the light-emitting diodes 1 emit red light to provide a tail light function and a brake light function.
  • the light-emitting diodes 2 of the second group may be formed, if necessary, at least in part as so-called duo light-emitting diodes, which may be illuminated in two different colors to provide a direction indicator which shines in a different color, usually orange, than the light-emitting diodes for the tail light function and the brake light function, as is the case with European vehicles. If the Direction indicator is designed as a flashing light that shines in the same color as the tail and brake light, as is the case with US vehicles, no duo LEDs are required.
  • the control unit can control the tail light in such a way that relevant illumination functions can be provided:
  • the light emitting diodes 1 and 2 of the first and second groups are illuminated in a first lower brightness in the same color, i. H. here in red. It is thus emitted a disc-shaped radiating surface with a homogeneous brightness through the lens 5.
  • the light sources 1 of the first group are controlled so that they shine brighter than is the case with the tail light function. In this case, therefore, the light characteristic of a bright central disc appears, which is surrounded by a less bright circular ring, which shines in the same color.
  • the brightness of the light emitting diodes 2 of the second group or a part of these light emitting diodes 2 is increased intermittently. If a direction indicator is to be provided which illuminates in a different color, the duo LEDs are driven so that the second color of these LEDs 2 intermittently, i. as a flashing light, it lights up. The other color of the tail light, which is provided in this case by the duo LEDs 2, remains unaffected.
  • the radiating surface for the light function of the direction indicator thus completely or partially surrounds the radiating surface for the light function of the brake light. For example, a full circular ring or a semicircular ring of the LEDs 2 may blink to provide the direction indicator.
  • the board 11 in the region of the dashed line T of Fig. 3 has a slot which separates the first region 3 and the second region 4 of the board 11.
  • the two areas 3 and 4 are connected by webs which interrupt the slot.
  • areas 3 and 4 are not connected by webs, so that two separate boards would be present.
