Abstract

A headlight for a motor vehicle includes at least two light sources and a driver, which is arranged to vary the light intensities of the light sources with a phase shift to one another periodically between a minimum and a maximum and in the course of a period to set intermediate values between the maximum and the minimum. In a phase of the period, in which the first light source reaches the maximum of its light intensity, the light intensity of the second light source is situated at an intermediate value and increases.
