This paper presents the development of smart road line lamp system consisting light control device. It can perform the individual power control or partial on/off control of a LED lamp by control center and can detect the error of the LEDs by current sensing . Also, the ability to control the brightness and period of on/off by detecting the car's existence. This light control circuit consists of road line lamp unit device. It can give a lot of solutions when the server, which controls the whole system, is operated through CDMA(Code-Division Multiple Access) network
