A method for controlling a motor-vehicle lighting device is provided that uses LEDs supplied with PWM signals temporally spaced apart from one another by a first time phase tand a second time phase t. An interval of interest is defined in which an electromagnetic disturbance must not exceed a maximum threshold value &#x3b8;max; driving signals are supplied on the basis of first phases tand tcomputed; and the measured or simulated waveform of the electromagnetic disturbance deriving from the phases tand tis compared with the maximum threshold value within the interval of interest defined. Where the waveform of the disturbance exceeds the threshold, two phases tand t, once again different from one another, are recalculated; otherwise, the last phases tand tcalculated are selected and used in the PWM control. An advantageous motor-vehicle lighting device is also provided.
