Abstract
The apparatus for automatically adjusting horizontally a direction of a light axis of a vehicle headlight of the invention includes a steering angle sensor detecting a steering angle of a steering wheel of a vehicle, a swivel control unit performing a swivel control by which the direction of the light axis of the headlight is adjusted horizontally depending on the steering angle of the steering wheel, and an abnormality detecting unit detecting an abnormality associated with the apparatus. Even after detection of abnormality associated with the apparatus by the abnormality detecting unit, the swivel control unit continues performing the swivel control until the light axis is returned to a predetermined initial direction in order to avoid abrupt change of the direction of the light axis of the headlight. The swivel control unit halts the swivel control after the light axis is returned to the predetermined initial direction.
