<p>PURPOSE:To provide an automatic dimming device which automatically turns on the direction indication lamp, and switches the headlight from the traveling beam to the passing beam depending upon the vehicle speed and dims the light. CONSTITUTION:The automatic dimming device for a headlight is constituted of a battery 44 for supplying the electric power to the headlight and a direction indication lamp, headlight putting-ON circuit, direction indication lamp putting-ON circuit 42 for putting ON the right or left direction indication lamp, car speed detecting circuit 52 which generates the output signal from the relation of the vehicle speed for a previously determined standard speed, and a dimming control circuit 50, and the dimming control circuit 50 puts ON either a right direction indication lamp putting ON signal or a left direction indication lamp putting ON signal. When the car speed detecting circuit 52 detects the traveling speed less than a standard speed, a prescribed output is supplied to a dimmer switch 48, and switches the traveling beam to the passing beam.</p> |
