Abstract: Output of each sensor arrangement is supplied to an ECU through a communication bus line. A value of a turning radius of a vehicle, which is used for adjusting directions of optical axes of swivel lights, is computed based on the output of each sensor arrangement in the ECU. When a majority of the computed values fall within a predetermined allowable range, the majority of the computed values are determined as normal, and the remaining of the computed values is determined as abnormal. The communication bus line is determined as abnormal when none of the output from the sensor arrangements is obtained. An optical axis control angle is computed based on the normal computed values and is used to drive actuators to adjust directions of the optical axes of the swivel lights.

Abstract: In such a state that a self-vehicle runs along a guide route (YES in S6), if an intersection is not present in a forward part for a while (NO in S8), beam control is carried out in a navigation associating mode corresponding to the guide route (S9). Consequently, beam irradiation is properly carried out over a road provided ahead of the vehicle without requiring a complicated calculation for the beam control. On the other hand, if the intersection is present in the forward part of the guide route (YES in S8), the beam control is carried out in a normal mode (a control mode other than the navigation associating mode) (S10). Consequently, even if the self-vehicle gets out of the guide route when passing through the intersection, the beam control itself is performed continuously and the beam irradiation is properly executed over the road provided ahead of the vehicle.
