We carry three HID kits. Here is how they differ:

  • X-treme Performance 55W AC: single-beam kit for a low beam, high beam or fog socket.
  • Bi-Xenon 55W AC: for headlights that use one bulb for both low and high beam, such as H4 or 9007.
  • X6 CANBUS 35W: lower wattage, built for vehicles that show bulb-out warnings.

Pick the bulb size your headlight uses on the product page. Some vehicles also need a relay harness to stop flicker. Spare parts are in ballasts and HID bulbs. Prefer LED? See LED conversion kits.

Free shipping to the lower 48. 30-day returns with an RMA. Questions? Call 702-988-6800, Mon-Fri 8am-3pm PT.

FAQ

Should I get a 35W or 55W HID kit?
35W runs cooler and suits most cars, and the X6 adds CANBUS for newer vehicles. 55W is brighter and draws more power, so it is often paired with a relay harness.

What is a Bi-Xenon HID kit?
It is for dual-beam bulbs like H4 and 9007, where one bulb handles low and high beam. The bulb moves its shield to switch beams, so you keep both functions.

Do I need a relay harness?
Many vehicles do not. If the lights flicker or will not start, a relay harness feeds the ballasts straight from the battery. We sell them by bulb size.
