1. A method for operating a motor vehicle, wherein the motor vehicle has a lighting device comprising two headlight devices, wherein the two headlight devices are arranged horizontally offset on a front side of the motor vehicle, and wherein each of the two headlight devices includes a lamp that is dimmable, the method comprising:
illuminating, by each of the two headlight devices, a spatial region extending in front of the motor vehicle over a horizontal angular range according to a respective brightness generated by the lamps;
before or during a reverse travel of the motor vehicle:
adjusting the brightness of the lamp of at least one of the two headlight devices as a function of a steering angle of the motor vehicle; and
at least one of:
if the two headlight devices comprise multiple lamps:
adjusting the multiple lamps such that a portion of the spatial region opposite a direction of the turning of the steering wheel is illuminated at an increased brightness, the multiple lamps each illuminating different portions of the spatial region; and
illuminating, at a reduced brightness, another portion of the spatial region lying in the direction of the turning of the steering wheel; or
dimming the brightness of at least one lamp of the two headlight devices arranged in the direction of the steering angle.
 
14. A motor vehicle comprising:
a lighting device including two headlight devices; and
a control unit for controlling the lighting device, wherein the two headlight devices are arranged horizontally offset on a front side of the motor vehicle, and wherein each of the two headlight devices includes a lamp that is dimmable, the control unit being configured to:
illuminate, by each of the two headlight devices, a spatial region extending in front of the motor vehicle over a horizontal angular range according to a respective brightness generated by the lamps;
before or during a reverse travel of the motor vehicle:
adjust the brightness of the lamp of at least one of the two headlight devices as a function of a steering angle of the motor vehicle; and
at least one of:
if the two headlight devices comprise multiple lamps:
adjust the multiple lamps such that a portion of the spatial region opposite a direction of the turning of the steering wheel is illuminated at an increased brightness, the multiple lamps each illuminating different portions of the spatial region; and
illuminate, at a reduced brightness, another portion of the spatial region lying in the direction of the turning of the steering wheel; or
dim the brightness of at least one lamp of the two headlight devices arranged in the direction of the steering angle.
