182 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.
