A plurality of light emitting display units(20) is operated by a power source supplied in the power supply unit, and is installed on a highway into a fixed interval. A controller(30) controls the light emitting display units by controlling the power source of the power supply unit. A generator(12) generates a power source by using a natural energy. A voltage regulator(14) receives an electricity generated in the generator, and controls the electricity into a set voltage. An electric condenser(16) charges a controlled electricity. A power distribution box(18) supplies one electricity among the controlled electricity and a charged electricity to the controller.
