A high intensity discharge (HID) lamp is a type of bulb that produces a bright light. These bulbs do not contain filament as they are based on gas discharge principal. The Xenon gas is ignited to produce an arc of light when high voltage is applied. This gas belongs to noble gases which mean it is colorless, non-toxic and chemically inert. Considering that vehicles use 12 volt electrical system for the lamps, HIDs require ballasts with igniters. The igniter generates a train of very high voltage (23000V) pulses which cause the gas inside the lamp to break down and ionize. The moment the gas ionizes, it will conduct electrical current at a much lower voltage, and then the high frequency AC output of the ballast continues to keep it ionized and in operation. In this mode, the voltage present across the lamp's terminals is around 85V (depending on the lamp and application) due to low resistance of the lamps.
Single Beam HID
Replace Bulb Type: H1/ H3 / H3C / H4-1(HB2) / H7 / H8 /H9 / H10 / H11/ 9004 / 9005(HB3) / 9006(HB4) / 9007-1 / 880 / 881/ 893 / D2C/ R/S, etc.
There are vehicles that require one bulb for High beams and another bulb for Low Beams. This means that the vehicle is equipped with Single Beam bulbs (e.g. 2016 Honda Pilot, 2015 Nissan Altima, 2009 Mercedes-Benz C230, 2007 Ford Edge, 2004 Chevrolet Classic).Single Beam bulbs trigger High beams, Low beams or Fog lights. In this case you need two kits to upgrade your headlights and one kit for the fog lights.
Dual Beam HID
Replace Bulb Type: H4 / 9004 / 9007 /H13
If a vehicle uses a single bulb for High and Low beams, a Dual Beam bulb is needed (e.g. 2016 Nissan Frontier, 2015 Nissan NV1500, 2009 Jeep Patriot, 2006 Nissan Frontier, 2003 Ford Ranger). Our Dual Beam bulbs are available in Bi-Xenon and Low Xenon/High halogen bulbs. These bulbs trigger High and Low Beams, while using one bulb.
With Low Xenon/High Halogen bulb type you will have 2 bulbs on one base. One bulb is Xenon, which is used for the Low beam and the other bulb is Halogen, used for the High beam.
Bi-Xenon bulbs convert both beams (Low and High) into Xenon, using the same bulb. This type of the bulb uses an electromagnet which is controlled with the help of a Bi-Xenon relay harness to change the physical position of the HID bulb for the low beam as well as high beam. With its help the focal length of the bulb and light output is adjusted. For a High beam a wide angle is needed and more focused light for low beam.
