HID or High Intensity Discharge uses an electrical charge to ignite Xenon gas contained in a sealed bulb. HID bulbs do not have filaments. The HID bulb is filled with a mixture of gassed including Xenon. When the HID bulb is ignited, an arc is created between the two electrodes. HID Extreme's HID kits are not simply a replacement bulb. Your new HID conversion kit will include new bulbs, electronic starters along with a very high voltage Ballast.
