The invention relates to an automatic high beam switcher, which belongs to the technical field of automotive auxiliary equipment. The automatic high beam switcher comprises an integrated control chip, a control relay and the like, and the automatic high beam switcher is characterized in that the integrated control chip controls pins to connect in parallel with a divider resistor and a light sensitive resistor by a current-limiting resistor; power supply pins 4 and 8 of the integrated control chip are connected in parallel with the divider resistor and the negative end of an anti-reverse diode; the positive end of the anti-reverse diode is connected with a power source; a pin 5 of the integrated control chip is grounded by a capacitor; an output signal pin 3 of the integrated control chip is connected in parallel with the control relay and the negative end of the anti-reverse diode; the other end of the control relay and the positive end of the anti-reverse diode are grounded; and an automatic/manual switch is arranged between J-0 and J-2 contacts of the control relay. The automatic high beam switcher is less in used components and simple in structure, and realizes the automatic switching of turning-on/off of a high beam, and therefore, the switcher is applicable to various vehicles such as saloon cars and trucks; and the automatic high beam switcher is strong in applicability and low in cost, and solves the problem that in the prior art, the manual control is operated frequently, and the switching efficiency is low.
