The LEDs 12 partially protrude from the receiving space 18 into the interior of the lamp. The one from the Beams emitted by LEDs are preferably used exclusively to the reflection surface 7, on which they are reflected to the lens 2. In this way, the entire lens 2 is illuminated indirectly. It is also possible to arrange the LEDs 12 so that the some of the rays they send out directly to the lens 2 and partially reach the reflection surface 7 on which they be reflected to the lens 2. In this way too Lens 2 optimally illuminated over its surface. The reflective surface 7 only needs in that area of the housing wall 1a to be provided, in which the emitted by the LEDs 12 Impact rays on the housing wall 1a. The lens 2 can in a desired shade can be kept, for example adjusted to the body color. It is also possible to use the LEDs 12 accordingly to colorize. Instead of the LEDs 12, neon tubes can also be Fluorescent tubes, incandescent lamps and the like can be used.

Im dargestellten Ausführungsbeispiel ist die Leuchte eine Komplettleuchte, die beispielsweise die Brems-, die Blink- und die Rückleuchte enthält. Es ist aber auch möglich, jede einzelne Leuchte so auszubilden, daß die Lichtscheibe in der beschriebenen Weise von den LEDs 12 direkt und indirekt beleuchtet wird. Die Lichtscheiben sind in diesem Fall entsprechend der Signalfarbe gelb (Blinklicht), rot (Brems- und Rücklicht) oder klar (Rückfahrlicht) eingefärbt, oder die LEDs haben einen entsprechenden Farbton. Die LEDs 11, 12 bzw. die zugehörigen Platinen 9, 17 sind an das Bordnetz des Kraftfahrzeuges angeschlossen.In the illustrated embodiment, the lamp is a complete lamp, which, for example, the brake, the turn signal and the rear light contains. However, it is also possible to use each individual lamp in this way train that the lens in the manner described by the LEDs 12 is illuminated directly and indirectly.
