PURPOSE: An apparatus for automatically controlling the light of a vehicle is provided to reduce installation fee by automatically controlling light brightness at a constant distance between one vehicle and another vehicle. CONSTITUTION: A light sensor part(110) changes the intensity of illumination into an electric signal by detecting the intensity of illumination in surroundings. A light sensing part transmits an electric signal to an interface unit. A receiving device(120) receives the transmission signal of a remote controller. A radio frequency module(130) demodulates the radio signal after amplifying the radio signal received from the light sensor part. A interface unit transmits an electric signal, which is transmitted from the radio frequency module, into a ETACS( Electronic Time Alarm Control System).
