Abstract: In the present system, mostly lightning up of highways is done through High Intensity Discharge Lamps (HID), whose energy consumption is high. It's intensity cannot be controlled according to the requirement so there is a need to switch on to alternative method of lightning systemi.e by using LEDs (Light Emitting Diodes). This system is built to overcome the present drawback of HID lamps. This system demonstrates the usage of the LEDs as the light source powered through solar panel with its variable intensity control as per the requirement. A cluster of LEDs are used to form a street light. The ATMEGA 16 contains programmable instructions which controls the intensity of LEDs based on the LDR sensor signals generated. The intensity of LEDs can be varied depending on the requirement of light on highways, thus saving electrical energy
