Abstract
A vehicle headlight apparatus receives road data from a navigation system. The apparatus has a first and a second swivel devices for adjusting an optical axis directions of a main light and a sub-light corresponding to one and the other headlights of a right and a left headlights, respectively. The apparatus also has a control unit, which separately controls the first and the second swivel devices, so that a one-eye navigation-cooperated control operation can be carried out which adjusts only the optical axis direction of the main light to be coincident with a road direction calculated based upon the road data.
