Abstract
A vehicle lighting apparatus includes means for controlling a deflection angle of a lamp which controls the deflection angle based on an output from a steering angle sensor for detecting the steering direction. The maximum deflection angle is controlled based on a vehicle speed detected by a vehicle speed sensor. When the vehicle is almost in a state of coming to stop, the maximum deflection angle is set to 0°, and the direction of radiation of the lamp is fixed in the straight ahead direction of the vehicle. When the vehicle is in the state of cruising almost at a high speed, the maximum deflection angle is suppressed with increase in vehicle speed, and thus the deflection angle of the lamp is controlled within the angle range around the straight ahead direction, thereby preventing lateral fluctuation of the deflecting direction of the lamp.
