One object of the present invention is to provide a headlight control system. The headlight control system is configured to be used with a headlight of a vehicle. The headlight control system includes a first light sensor, a microcontroller, a first driving motor, a power module and an optical lens module. The optical lens module is disposed in front of the headlight in order to receive illumination of the headlight. The microcontroller is electrically connected to the first light source sensor and configured to receive a signal transmitted by the first light sensor. The first driving motor is electrically connected to the microcontroller. The first driving motor is configured to follow an instruction from the microcontroller to drive a first driving mechanism. The first driving mechanism is configured to adjust the optical lens module upon being driven by the first driving motor. The power module is electrically connected to the microcontroller and the headlight. The power module is configured to follow an instruction from the microcontroller to supply the power to the headlight.
