PIC107 Street light that glows showing the road ahead for ½ km only on sensing vehicles or any movement (Using PIC Microcontroller): Light Emitting Diode (LED) replaces HID lamps by engaging a programmable microcontroller that controls intensity by pulse width modulation which enables energy saving during late nights considering low traffic density. The pulse width becomes very narrow on sensing no movement of vehicles. As the vehicle forwards, the intensity goes on increasing for few lights ahead and as it passes away the intensity goes on falling.
