Replacement Xenon HID Ballast for BMW, Mercedes, Audi, Land Rover Headlight Control Unit Module Replaces 307 329 074, 63127176068, 307 329 090, & others - Warranty

I bought this for my 2005 Range Rover when my left headlight went out and switching out the bulb didn't solve it. Perfect fit, plugged right in, still works as expected months after installing. That's a win.

This Ballast also known as "Range Control Module" by VW is an exact replacement. If you have a headlamp go out on one side, switch the bulb that works into the side that doesn't; If that don't work then swap out the ignitor & if that doesn't work then you are likely looking at the ballast mounted on the bottom of the headlight assembly, you must remove the assy. by removing the grille, all screws on the TOP & 2 in upper wheel well of the bumper cover, un-clip the cover on each side pushing cover forward at the wheel well ( leave the screws in the bottom of the cover so it won't come completely off & pull it down in front of each headlight to access 1 (F%$&@) screw hidden behind cover on bottom of headlight, 2 others (top outside & middle inside) are easier to get to (all are T-20 or 25 torx), then unplug main power harness (big plug back of headlight) it has small locks on top & bottom of connector meant to squeeze together to release, you will break them, they have become very brittle, this will not harm the re-installation because the connector has a substantial sealing gasket ring that will retain it just fine. Once light assys. are removed swap the good side ballast with the non-working side slip it back in the hole far enough to plug the harness in & try it if it work you need this ballast. Thanks for the great price, Ronnie...

Purchased this to replace a headlight in my sons VW GTI after he hit a deer. The new headlight assembly did not come with the HID bulb, ballast or igniter. This unit was an exact fit for the original which was completely destroyed in the collision. I also purchased an aftermarket ignitor along with a genuine VW bulb. At first the light would not come on and after swapping parts with the other headlight, I determined it was the aftermarket ignitor. I sent that back and got a VW ignitor and everything worked, so make sure if you replace everything and it doesn't work, to swap out parts with a working light to determine the root cause of the issue. I am happy with this ballast, it was reasonably priced and shipped quickly.

My driver side HID was having issues in the cold, then eventually just died. I assumed it was the original bulb. Replaced that, no dice. So then I assumed it was the igniter. Tore the headlight apart and replaced that with an OE one that wasn't great. It worked for three weeks, then died again. At that point it was either a failed igniter or ballast. BMW originals are several hundred, and on a 20 year old car, how much are I willing to spend...I assumed the igniter killed the old ballast and took a shot on this one.Installed it a few weeks back and it's been going strong. The driver side light output is actually brighter than the passenger side. Either my passenger side is going to die soon, or this one just got it back to the original brightness that I haven't had for years.All in all. As long as it keeps trucking along with all three new components, I'll have no complaints. Definitely saved me a lot of $$$ around the holidays. Once my other side kicks the bucket I'll be ordering another one.

Listen I needed a quick fix for my headlight for inspection, we narrowed it down, that is was what we needed to fix it. We went to the local auto stores and online and everyone wanted close to $400 for this one part. We went junk yard hopping and still couldn't find the correct part. Finally I bought this think if it doesn't work I'll return it, or maybe it will just get me through inspection, an let Me tell you, that damn light is still on. Quick, quality and good for the price. Would buy again.

The item came in on time. Replace the ballast for my 2003 Mercedes S500 on the right front head light. Solve the problem and enjoy my head lights again. Good product and save a lot of moneys.Thank you!

Installed and worked great... for about three days. Then puked out. Buy the real one, I realize it’s three times the cost but what is your time and piece of mind worth. Regretting purchase...
