The method involves releasing a light beam (13) in a vehicle longitudinal direction from a road surface (20) at preset angle (delta) with respect to a reference axle (21) by a light unit (14) such that the beam is reflected at the surface. The reflected beam is received, and road surface grade (gamma) of an imminent road surface section (25) of the road surface is determined with respect to a momentary road surface section (24) on which a motor vehicle is provided based on the beam. Orientation (4) of a light emitted from a right headlamp (2) is adjusted based on the road surface grade. An independent claim is also included for a device for automatic adjustment of orientation of a light emitted by a headlamp of a motor vehicle.
