Abstract

PURPOSE:To improve safety and reliability by restoring the lighting direction of a lighting means to a forward direction by outputting a prescribed restoration signal when a control signal having a pulse width corresponding to the steering angle of a steering wheel is not inputted after the completion of a prescribed cycle. CONSTITUTION:The steering state of a steering wheel is detected by the detecting means 1 and 2, and the detection signal is inputted into a control signal generating circuit 3. The control signal supplied from the control signal generating circuit 3 is outputted into a motor control circuit 4, and an electric motor 46 is driven to change the lighting direction of the head lamps. In this case, a fail-safe circuit 4A and a servomotor control circuit 48 are installed in the motor control circuit 4. A plurality of AND gates AND1 and AND2. OR gate OR1 and others are installed in the fail-safe circuit 4A, and an electric signal (restoration signal) having a prescribed pulse form is inputted into the AND gate AND2 from an oscillator OS.
