Title:
DEVICE FOR AUTOMATICALLY TURNING VEHICLE HEAD LAMP ON AND OFF
Document Type and Number:
Japanese Patent JPH01240337
Kind Code:
A
Abstract:
PURPOSE:To automatically turn head lamps on and off answering to the running and stand-still of a vehicle as well as to improve safety and the like by inserting a plug with a specified electric circuit equipped with an oscillation sensor into a cigar lighter charging hole of the vehicle. CONSTITUTION:A plug 2 is inserted into a cigar lighter charging hole, a plus circuit X1 connected with the plus terminal 2X of the plug 2 is connected with a constant voltage three terminal regulator Re, a transistor TR1 and an oscillation sensor SE1 in series, and the transistor TR1 is connected with a resistor R in parallel. In addition, a circuit in which a circuit X1 between the regulator Re and the transistor TR1, two integral circuits IC1 and IC2, a capacitor C1, a diode D1, three transistors TR2 through TR4 and a head lamp switch SW are connected in series, is connected with the plus circuit X1 in parallel. And when oscillation is detected by the oscillation sensor SE1, each transistor TR2 through TR4 is turned off so that the switch SW is turned on.
