Abstract: In the vehicle lighting control apparatus and method, it is determined that the user's steering wheel is returned from a steering angle existing in a saturated steering angle region toward a neutral steering angle region at a given speed or more. If such a steering condition is found, a swivel angle is calculated based on a swivel-angle control characteristic showing a monotonic decrease in the swivel angle when the steering angle decreases from the steering angle existing in the saturated steering angle range to a third preset angle.
