Abstract
A vehicle lighting apparatus includes abnormality detecting means for detecting abnormality in the AFS of the vehicle lighting apparatus, and means for adjusting optical axis of the lamp in the vertical direction for setting the angle of the optical axis of the lamp downward in the vertical direction in comparison with the reference angle upon receipt of abnormality-detected signal from the abnormality detecting means. When the vehicle lighting apparatus lapsed into malfunction, by tilting the optical axis of the lamp in the deflected state downward in the vertical direction, the lamp is prevented from dazzling oncoming cars even when the lamp is in the deflected state toward the oncoming cars, thereby realizing failsafe which is preferable in terms of traffic safety.
