The present invention relates to an input voltage stabilization circuit of a rear combination lamp, which includes: a light output unit including a plurality of organic light emitting diode (OLED) elements; a DC-DC converter unit for providing an output voltage suitable for driving the plurality of OLED elements by stepping up or down the voltage of a main power source supplied from a battery for a vehicle; and a feedback unit for providing information of the highest required voltage value among required voltage values of each of the plurality of OLED elements to the DC-DC converter unit as feedback, wherein the DC- DC converter unit controls the output voltage based on the feedback. Accordingly, the present invention can effectively transmit a signal without inducing the glare of a driver of the other vehicle.
