<p>PURPOSE:To switch a headlight and a small light automatically by outputting a current from a rotational speed detecting adapter interlocking with a speedometer, or stopping this output with the running or stopping of an automobile. CONSTITUTION:When a light combination switch 6 is set to an auto joint 9, a small light is lighted by wiring 10 connecting an interval between a first step joint 7 of the small light and the auto joint 9. When an automobile gets running, the current generated by an amplifier 5 of an adapter 1 flows into a relay 11 by way of another relay 12, thus a headlight is lighted. On the other hand, when the automobile is stopped temporarily, the current being generated out of the amplifier 5 of the adapter 1 runs short, and a switch circuit of the relay 11 is turned off, so that the headlight goes out, and the small light alone is continuously lighted. Therefore a switching between the headlight and the small light can be done automatically.</p> |
