Abstract:
1. Illumination device for vehicles comprising at least one light-emitting diode ( 3 ) and a light control unit (I), wherein the light control unit ( 1 ) is connected to the at least one light-emitting diode ( 3 ) and a pulse-width modulated clock signal (PWM) is generated with the light control unit ( 1 ) and transmitted to the at least one light-emitting diode ( 3 ); a circuit ( 2 ) arranged between the light control unit ( 1 ) and the at least one light-emitting diode ( 3 ), with which, depending on a control signal (S) received by the circuit ( 2 ), the pulse-width modulated clock signal (PWM) is fed via different resistors (R 1 , R 2 , R 3 ) to the at least one light-emitting diode ( 3 ).
