Electrically powered ON/OFF of street lighting has brought a sense of wellbeing and freedom from risk or danger but street lights in town centres, traffic lights and pedestrian crossings stay ON all night. This amount of lighting is not required in that it adds no benefit to the community. Continuous ON state of street light leads to power wastage. In other case, it is getting very difficult to analyze the failure of street lights in all places. In this Paper we have analyzed these problems. This paper consists of a group of measuring stations in the street (one station located in each lamppost) and a base station located nearby. The measuring stations are used to observe street conditions as the intensity of daylight and, depending on the conditions they activate or off the lamps. For these reasons every lamp is designed independent to decide about the activation of light. The base station continuously checks for proper operation of the lamp and sends the information using the wireless network to the operator.
