The invention discloses a night automatic switch for an automotive high beam. The night automatic switch for the automotive high beam comprises a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a seventh resistor, an eighth resistor, a ninth resistor, a tenth resistor, a first amplifier, a second amplifier, a third amplifier, a fourth amplifier, a fifth amplifier, a first capacitor, a second capacitor, a photocell, a first diode, a second diode, a potentiometer, a triode and a time-base chip. By the adoption of the night automatic switch, traveling can be safer, when an automotive lamp of an automobile on the opposite side irradiates the photocell G of the automobile, electrodynamic potential is generated on the photocell, the automotive lamp emits high beams for 1.9 seconds and emits low beams for 1.9 seconds alternately under the condition, the intensity of the beams is proper so that dazzling can be prevented for a driver, and normal work of the automatic switch can be prevented from being disturbed by stray light.
