<p>PURPOSE:To ensure a field of view sufficient for retreat of a vehicle in front of the vehicle by changing the irradiating direction of a lighting means to half- steering direction in interlocking relation with steering wheel operation in the retreat of vehicle. CONSTITUTION:When a fog switch 6 is turned on, left and right fog lamps 7, 8 are lit. When a vehicle is steered right by a steering wheel under such a condition for example, the contact 1a of a steering sensor 1 is closed when the steering exceeds a predetermined angle. Then, a transistor Q1 in a right lamp drive signal processing circuit 21 is turned on so that the irradiating direction of right lamp 7 is moved right by the operation of a DC motor 32 in a right lamp drive unit 3. On the other hand, a backup switch 10 is closed in the retreat of vehicle and a transistor Q3 in a backup-signal processing circuit 23 is turned on, so that, when the contact 1a is closed, the potential level of an output terminal 242 in a decoder 24 becomes L to operate a left lamp drive signal processing circuit 22.</p> |
