A well-designed, energy-efficient street lighting system should permit users to travel at night with good visibility, in safety and comfort, while reducing energy use and costs and enhancing the appearance of the neighbourhood. These cost savings can also enable municipalities to expand street lighting to additional areas, increasing access to lighting in low-income and other underserved areas. In addition, improvements in lighting quality and expansion in services can improve safety conditions for both vehicle traffic and pedestrians. The system was programmed to automatically turn off during the hours of daylight and only operate during the night. The brightness of the LED streetlight is inversely proportional to the number of vehicles passing the entry point .When only single vehicle passes entry point, the streetlight glows with 100% brightness. When two vehicles passes the entry point, the brightness of the streetlight glows with 90% brightness .Similarly the brightness of the streetlight keeps on reducing depending on the number of vehicles till the brightness reaches the minimum value (say 50%) for visible vision. The minimum value of the brightness depends on different parameters like area, type of streetlight, etc. The brightness again increases as the vehicles exit the exit point of the road. There is another important part of the operation. It is the power generation mode. It consists of a solar panel which uses sun’s radiation as a source to produce power and a propeller. The propeller rotates due to motion of the vehicle and motion of the wind. The dynamometer connected to the propeller converts the mechanical energy into electrical energy, hence producing power.
