<p>PURPOSE:To miniaturaize a device by providing a relay for opening and closing electrifying circuits to a high beam heater and a low beam heater and a relay for switching said electrifying circuit to the high beam or low beam heater in accordance with the operation of lighting switch and a high beam switch. CONSTITUTION:When a lighting switch 53 is turned on, a lighting circuit 55 and a starting circuit 56 are operated and a low beam lamp 54 is turned on. And, after a certain period of time, the operation of a second heater controlling relay 71 is stopped, starting to electrify a high beam heater 73. Next, when a high beam switch 57 is turned on, the operation of a first heater controlling relay 70 is stopped, stopping the electrification of the high beam heater 73. Also, by turning on the high beam switch 57, a lighting circuit 60 and a starting circuit 61 are operated, turning on a high beam 59. By this construction, the same control as using three heater controlling relays can be obtained by using two relays.</p> |
