ABSTRACT:
To accurately shade headlamp light for both a leading vehicle running on the same lane and an opposed vehicle running on an opposed lane, the headlight apparatus for an automotive vehicle comprises a movable headlamp, a light sensor attached on the pivotal headlamp for detecting presence of a leading vehicle, an adjusting mechanism for adjusting the optical axis of the headlamp, a controller for actuating the adjusting mechanism in response to sensor signals of the light sensor to move the headlamp so that angle of headlamp optical axis can be adjusted according to distance to a leading vehicle, and a shading plate disposed independently from the optical axis motion of the headlamp for shading light for an opposed vehicle.
