An apparatus for automatically adjusting the inclination of the light beam of a motor vehicle headlight -

摘要

The rear vehicle height HR is detected by the vehicle height sensor 11 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 30 is adjusted with reference to the pitch angle.
