The volume levels of 3 and 3 are close to each other (FIG. 3). The output of microphones 2 and 3 is
After being amplified to a predetermined level, it is applied to the comparator 8. The comparator 8 constantly compares the noise levels and sends out a matching output when the level difference is less than a predetermined value. That is, when the car 1 enters the tunnel, the difference in the noise levels from the microphones 2 and 3 becomes less than a predetermined value, and the comparator 8 detects that this state continues for a period of time corresponding to an internal time constant, for example, 1 to 3 seconds. Then it sends out the output. As a result, the make contact of the switch circuit 9 is closed and the headlight 10 is closed.
lights up, the break contact opens and the wiper 11 stops.
