The invention discloses an automatic light regulator. High-low beams of an automobile and a motorcycle are used in driving in dark night. The automatic light regulator can close light of an automobile under the irradiation of head-on strong light. A circuit is composed of a photoresistor, an electromagnet and a power source. When the photoresistor is affected by light, a contact P of the electromagnet is conducted to be in communication with a AB, and when the photoresistor is not affected by light, the contact P of the electromagnet is communicated with a CD; and the AB is a high beam switch contact, and the CD is low beam switch contact. As shown in the figure, the light regulator has the beneficial effects that driving at night is overcome, the problem that head-on automobile light and the light of the automobile bloom, and a driver cannot clearly see the current road is solved, and safety driving is achieved.
