PURPOSE: A cluster lighting stabilization system of a vehicle is provided to stabilize the light-emitting change of a light emitting diode of a cluster caused by external noise and load by separating the cluster and a ground of wires related to a vehicle lighting. CONSTITUTION: A cluster lighting stabilization system of a vehicle is composed of a light emitting circuit having a first lighting voltage unit(ILL-) determined to one of ground and open states according to a lighting mode and performing a luminous action of a light emitting diode(LED11,LED12) by receiving predetermined voltage; a first switching circuit having a second lighting voltage unit(ILL+) for deciding a voltage level according to the lighting mode and performing a switching motion according to the voltage level of the second lighting voltage unit; and a second switching circuit interlocking with the switching state of the first switching circuit and forming a first path having a ground using the first lighting voltage unit or a second path having a self-ground at the light emitting circuit.
