description The method involves terminating the brightness of semiconductor light sources within similar period of duration of pulse width-modulated signal. The semiconductor light sources whose brightness is to be adjusted, are switched ON at various points within the period of duration of pulse width modulated signal, and are switched OFF at common point. Independent claims are included for the following: (1) motor vehicle light valve; (2) headlight; and (3) motor vehicle illumination device.
