ABSTRACT:
An apparatus for adjusting a direction of a light axis of a swingable auxiliary headlight of a vehicle includes a steered angle sensor detecting a steered angle of a steering wheel of a vehicle, a vehicle speed sensor detecting a vehicle speed of the vehicle, a turning radius calculating device calculating a turning radius of the vehicle on the basis of the detected steered angle and the detected vehicle speed, and a control unit performing a swivel control by which the directions of the light axes of auxiliary headlights of the vehicle are adjusted to target directions determined depending on the detected steered angle and the detected vehicle speed. The control unit is configured to control the auxiliary headlights to be in an off state while the calculated turning radius shows a value equal to or larger than a predetermined threshold.
