| description | The present invention relates to an illumination device for vehicles with at least light-emitting diode ( 3 ) and a light control unit ( 1 ), 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) can be generated and transmitted to the at least one light-emitting diode ( 3 ) with the light control unit ( 1 ). The illumination device for vehicles according to the invention comprises a circuit ( 2 ) arranged between the light control unit ( 1 ) and the at least one light-emitting diode ( 3 ), with which, depending on the control signal (S), the pulse-width modulated clock signal (PWM) can be fed via different resistors (R 1 , R 2 , R 3 ) to the at least one light-emitting diode ( 3 ). The present invention further relates to a method for controlling an illumination device for vehicles with at least one light-emitting diode ( 3 ) and a light control unit ( 1 ). In the method according to the invention the light control unit ( 1 ) generates a pulse-width modulated clock signal (PWM), which the light control unit ( 1 ) transmits to a circuit ( 2 ). The circuit receives a control signal (S) and, depending on the control signal (S), feeds the pulse-width modulated clock signal to the at least one light-emitting diode ( 3 ) via different resistors (R 1 , R 2 , R 3 ). |
