2005-2007 Mercury Montego 654514868 D1R D1S Xenon Ballast Bulb Control Unit HID Bulb Generic

It was a direct replacement, and after installation, the headlights were properly adjusted and functioning again. No more flickering or error codes. A quality part to restore functionality to the car’s lighting system.

Replacing the LED ballast control unit was necessary for my lighting setup, and this unit delivered perfectly. The control unit effectively manages the ballast, preventing any flickering.

It was well packaged and arrived in excellent condition. The headlights now operate at their full potential, offering improved visibility and performance.

Kit was Excellent

I have a 2019 Alloy Edition Chrysler 300S, 5.7L Hemi and all the bells and whistles to go with it. I understand keeping up with maintenance and all the required checks that go into maintaining peak performance on a vehicle. Spending the money on all those things, I have no issues, but when a simple bulb and ballast cost more then a performance chip, cold air intake and other things that you would love to spend your money on, I couldn't see spending the money on something that only lights up the road (bright useable headlights a plus).

I looked all over for a better price than what the dealer wanted. I try and go OEM (manufacturer specs) as much as possible just to maintain the quality of the product that I put in the car. But in my research I decided to purchase the ballast and bulb from UCarPart and give it a try since it was almost 1/10th of the cost from the dealer.

The car is equipped with Adaptive Bi-XENON HID headlamps, it took about 10 minutes to remove the bumper (did not disconnect all the sensor wires, I just braced a bag to hold the bumper and removed the four screws holding the housing), and 2 minutes to change the parts and another 10 minutes to put the car back together (30 minutes tops). Saved tons of money doing the labor and buying the parts from UCarPart (Purchased two sets). When you get the new part just make sure that you match all the specifications from the old ballast to the new one so that you know the voltage will work out just fine. That's if your ballast goes out, if its just the bulb then you don't have to remove the bumper just open the cover from the inside of the engine bay and replace the bulb itself.

Overall, I am completely satisfied with the results of the replacement parts. 100% recommended!
