<p>PURPOSE:To fix an illuminating angle position of right and left headlamps in the same position as it is without providing any special signal line, when an abnormal condition occurs to at least one of signals from an illuminating angle position setting device. CONSTITUTION:A setting device 1-1, right and left headlamp driving units 2-1, 3-1 are constructed as shown in a figure. When a line L1 is broken during an adjusting operation of an illuminating angle position, a P1R point voltage VSpR in the driving unit 2-1 is abnormally increased, and an output of CP1R becomes (L), and then, a motor MR is stopped. On the other hand, a voltage V1 in a point PO is abnormally reduced. In this way, a voltage VSpL of a point P1L is abnormally increased, and an output of CP1L becomes (L), so that a motor ML is stopped.</p> |
