Abstract

The present invention provides, as one aspect, a light control apparatus for controlling directions of optical axes of headlights mounted in a vehicle. The apparatus includes a position detecting section that detects positions of the headlights with respect to a road surface, an optical axis direction calculating section that calculates the directions of the optical axes of the headlights, individually, so that the optical axes are directed to illumination targets positioned at predetermined distances from the positions of the headlights detected by the position detecting section, a leveling control section that controls the directions of the optical axes of the headlights in the vertical direction, individually, and a leveling output section that outputs a control command based on a calculation result of the optical axis direction calculating section to the leveling control section.
