Abstract
A vehicle lighting apparatus includes lamp deflection angle controlling means for controlling the change of a deflection angle of a lamp. The vehicle lighting apparatus further includes a reference angular position setting means for setting the deflection angle of the lamp to a predetermined reference angular position when a deflection angle detecting means for detecting the deflection angle of the lamp is broken down. When the deflection angle of the lamp cannot be detected in an adaptive front-lighting system (AFS), and thus the AFS lapsed into malfunction, the deflection angle of the lamp is fixed to a reference position obtained by rotating a motor for deflecting the lamp in one direction to the locked state, and from this locked state, rotating by the given amount in the reverse direction.
