Abstract
In a vehicle headlight optical axis adjusting apparatus, inter-vehicle distance in each of divided zones is detected by a laser radar device. Desired optical axis raising angles for a vehicle headlight are calculated based on these inter-vehicle distances of the divided zones. The optical axis of the headlight is adjusted to the most downward pointing angle selected from among these angles, so that a driver of a preceding vehicle is not blinded.
