Abstract

A method is provided for operating a headlight having a laser light source in a motor vehicle. The headlight generates a light distribution from the light of the laser light source. The laser light source is activated such that the operating power of the laser light source is switched from a first power value to a deactivated operating state or is lowered to a second power value when the speed of the motor vehicle falls below a first speed threshold. The operating power of the laser light source is increased from the deactivated operating state or from the second power value to the first power value, when the speed of the motor vehicle exceeds a second speed threshold, which is greater than or equal to the first speed threshold.
