Abstract
A motor vehicle headlight with at least one modulable laser light source, whose laser beam is directed onto a means of light conversion through a means of beam deflection controlled by a beam deflection control, and with a projection system to project the light image produced by the means of light conversion onto the road, wherein a first group of at least two laser light sources is provided to produce a first group of at least two essentially horizontal light bands lying on top of one another on the means of light conversion and a second group of at least two laser light sources is provided to produce a second group of at least two essentially horizontal light bands lying on top of one another on the means of light conversion, wherein the light bands of the first group and the light bands of the second group overlap one another.
