High Intensity Discharge (HID) is a new type of lighting technology that's primarily different from the conventional halogen bulbs that use a heated tungsten filament. Unlike Halogen lamps, High-Intensity-Discharge (HID) lamps don't have a filament but create light by the arc between two electrodes. The arc activates the Xenon, which in turn ignites the metal halide. The light produced by an HID Xenon lighting system is greater than a standard halogen bulb and with less power consumption. HID Xenon lighting systems appear as a bright white beam which resembles natural daylight. The bright white beam offers greater visibility and is now being used on modern motor vehicles.

In an HID Xenon lighting system, the voltage between the two electrodes rises firstly from 12V to 23000V and keeps stable at 8000V by using the Xenon HID ballasts system. Due to the ultra high voltage, the Xenon gas ionises and a super-bright beam is produced, whose colour temperature is up to 12000K. The HID Xenon lighting is much more economic, more stable and much brighter than any conventional lighting.
