Abstract
The rear vehicle height HR is detected by the vehicle height sensor as vehicle inclination information by a CPU. Based on the rear vehicle height HR, the inclination angle of the headlight optical axis direction is computed with an inherent control constant corresponding to vehicle specifications preset by a specification discrimination signal. Then, the headlight optical axis direction is adjusted with reference to the pitch angle.
