This HID polarity conversion relay can solve these problems, so you can work your headlights normally.
2. H4 Hi Low Switch HID Kit for Phillips Control is useful when installing negative control vehicles.The polarity conversion relay is inserted directly and the negative is positive, positive is negative, easy to use.

Inadequate packaging.

The item quality is ok, unfortunately the packaging is inadequate. One of our lights was cracked on arrival. The Company was helpful in providing a replacement which took a while, only for the replacement to arrive badly damaged. Hoping for a resolution once more.

Die Passgenauigkeit der Aftermarket ist natürlich nicht mit Orginalem zu vergleichen. Preis und ist demnach gut!

Although it is an aftermarket part, it fits perfectly. There are no gaps after installation, and the quality feels decent. I hope it can last a long time.

The lamp housing is well-made with solid sealing, no fogging or water intrusion even after heavy rain.

Great waterproof build.

Great waterproof build. Heavy rain and car washes haven’t caused any moisture buildup inside the lamp.

Replaced my dim stock headlights, the light cuts are clean and won’t blind oncoming traffic at night.

Love it

What impresses me most is the small thoughtful details, like extra spare sealing gaskets and reinforced wiring. The light color temperature is soft white, so my eyes don’t get tired during long evening drives. Zero dark spots or uneven light spread on the road surface.

Got tons of compliments from friends after I installed them. The black housing matches my front grille perfectly, no ugly gaps between the light and bumper. Light spread is smooth with no dark blind spots.

My factory headlights faded and turned yellow after years of use, so I picked up this LED replacement set. The install process was surprisingly easy, around half an hour with basic hand tools. The beam pattern is well-calibrated, bright enough for dark highways without glaring other drivers. No moisture trapped inside the sealed housing even after multiple thunderstorms. Very happy with this simple yet effective upgrade.

Stuck in high beam

Not sure if it's my car, or the bulbs supplied... My car's headlights are stuck in high beam since the change. Could be a the computer, although I though the ballast was the part to operate the globes...
All fit the car well, just not sure what's going on.

Fits just fine. Works properly as long as the plug is seated all the way. If not light is very dim to almost not at all. Also some coding needed if replacing halogen housings. BimmerCode to the rescue on that one even though it added an extra $133 for the OBD2 adapter and app. Would’ve gained an extra star or two if it was a true “plug and play” setup with no coding

Compared several brands and this one has the sturdiest mounting brackets. No loose shakes when driving on bumpy roads. Overall fantastic value vs dealership OEM headlights.

Everything I needed for install came in the box, no extra gaskets or adapters to buy separately. Alignment was perfect right out of the box, I didn’t even adjust the beam height afterward.
