Abstract
PURPOSE:To prevent the lighting of high beams and obviate traffic accidents due to dazzling light to cars on the opposite lane by a method wherein a head light is surely regulated to low beams when a light switch is turned ON after the switch is once turned OFF. CONSTITUTION:When a light switch 4 is turned ON, a transistor Tr1 of a light signal detecting circuit 13 is switched ON first, and an operational amplifier 14 emits pulse signals by the ON of the transistor Tr1 to switch a transistor Tr2 ON. Signals are transmitted to a set terminal S of a control circuit 11 by the ON of the transistor Tr2, and an output terminal Q of a flip-flop circuit 12 is set at line potential and an output terminal Q at earth potential. Consequently, since the terminal Q is earth potential, the transistors Tr3, Tr4 of an amplification circuit 8 are both switched OFF. Thus, since the actuator 10 is turned ON to a low-beam circuit 6 by the nonfunctioning of a relay 9, a low-beam light 3 is lit.
