PURPOSE: A control method of light for a vehicle is provided to maintain light of equal brightness without regard to positions of vehicles and kinds of light resources. CONSTITUTION: In a rheostat exposure, an exposure degree of a bulb lighting unit is controlled by a duty ratio input of a rheostat. An LED(Light Emitting Diode) lighting unit supplies power to an LED by receiving the duty ratio input of the rheostat from a microcomputer of an electronic device and adjusting the duty ratio input to a voltage vale corresponding to a bulb brightness. In controlling the rheostat, the LED lighting unit is controlled as same brightness as the brightness of the bulb. Thereby, the productivity of a vehicle is improved and the dazzling of a driver is prevented.
