Abstract
In a vehicle lighting apparatus in which the irradiation direction of lamps provided at the left and right portions of an automobile can be deflected to the left and right directions in association with the steering operation of a steering apparatus, the deflection angles of the left and right lamps are changed in different manners in accordance with a vehicle speed, for example. For example, at the time of steering to the right, when a vehicle speed is a predetermined value or less, only the right lamp is subjected to the deflecting operation, while when a vehicle speed exceeds the predetermined value, both the right and left lamps are simultaneously subjected to the deflecting operation. The deflection angles of the left and right lamps are differentiated in accordance with the speed change of an automobile. Thus, it can realize such irradiation that at the time of high speed traveling where an automobile travels while steering to the left and right, the visibility in an area ahead of an automobile is improved, while at the time of middle and low speed traveling, the visibility in an area just ahead of an automobile is improved.
