A motor vehicle includes a projection device to project a light distribution for driver information in the longitudinal direction of the motor vehicle onto the ground in front of the motor vehicle. The light function of the projected light distribution is different from a low beam and a high beam light. During operation of the projection device within a predefined interval of the vehicle speed in the forward direction of the motor vehicle, an increase in the extent of the light distribution in the longitudinal direction of the motor vehicle occurs as the vehicle speed increases. The extent of the light distribution at each vehicle speed is thereby greater than or equal to the extent at lower vehicle speeds.

Motor vehicle having a projection device

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.
