The HID & LED Depot specializes in automotive performance lighting including High Intensity Discharge Xenon lights commonly known as HID's. High-Intensity Discharge lamps make more visible light per unit of electric power consumed than fluorescent and incandescent lamps that come standard on most original vehicles. A light-emitting diode (LED) is a semiconductor light source. LEDs present many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching.
