Abstract
A vehicle headlight apparatus includes a headlight and an actuator. The actuator horizontally changes a direction of an optical axis of the headlight. The vehicle headlight apparatus detects a rotational state of at least one predetermined wheel. The vehicle headlight apparatus determines whether a vehicle travels in a forward direction or a non-forward direction based on a detection result. A swivel operation, in which the actuator horizontally changes the direction of the optical axis of the headlight based on a steering operation of the vehicle, is performed when the vehicle headlight apparatus determines that the vehicle travels in the forward direction. The swivel operation is cancelled when the vehicle headlight apparatus determines that the vehicle travels in the non-forward direction.
