PURPOSE:To halve the necessary number of lamps by providing a scanning beam douser and a low beam douser, and by driving them in such a way that when one is set to a predetermined position, the other is set to an ineffective position, at a douser driving part. CONSTITUTION:The condition where a low beam douser 4b is set to a predetermined position is depicted by a continuous line. In this case, a scanning beam douser 4a is pulled up by a lever mechanism 5 and is revolved upward at a hinge 4c as an axis, to be set to an ineffective position. The another condition where the douser 4a is set to a predetermined position is depicted by a dotted line, and in this case, the douser 4b is set to an ineffective position. A solenoid 6 is connected with the lever mechanism 5, either condition stated above can be chosen by a change-over switch provided in a driver's seat. Namely, when the solenoid 6 is driven, and the switching is executed for either the douser 4a or 4b through the lever mechanism, a scanning beam and a low beam can be obtained, and both of them are available with one lamp. |
