Abstract
The vehicular headlight apparatus includes a control means configured to change a light illumination area following a position of a detected target object until a shift angle between a reference direction and a direction to the target object with respect to a headlight is calculated to exceed a maximum limit shift angle, and configured to, when a vehicle speed is detected to exceed a predetermined threshold value, set the maximum limit shift angle to a small deflection angle, and change the present light illumination area to a low-beam light illumination area covered by the headlight in a low-beam state if the shift angle is calculated to exceed the maximum limit shift angle set to the small deflection angle.
