OEM 66340 OSRAM D3S Xenon HID Headlight Bulb

Great replacement hid for my 2014 Audi Q7, installed them myself and so far after a year, still working fine. They usually recommend replacing both at the same time. They are as bright as OEM Audi headlights.

This was much cheaper than buying it from the dealer and it is the exact OEM replacement bulb. I initially just replaced the bad bulb but after seeing how much brighter it was than the 6 year old other bulb that was still working I bought a second one to replace it, too. I installed them over a month ago and they work great. HID bulbs gradually fade over the years and you don't notice it until you put a new one side by side. If your bulbs are old just replace them both. Here are the before and after pics from replacing just one bulb and then both.

One headlight bulb turned orange color then died a few days later after 10 years of use.Replaced with this Osram 66340 in about 30 minutes and saved $$$ dealer would charge. Replacing the bulb is easy: unplug cable and quarter turn counterclockwise to remove then reverse order to install. Accessing the bulb is highly dependent on the bulb location in your vehicle. For me, it's accessed from wheel well and removing three screws are needed (two in tight spot using a low profile ratchet).The color temperature is slightly cooler than the old bulb which is expected. Overall very happy with the bulb and hopefully no need to replace it again for the rest useful life of the car.

installed and working perfectly

This fit perfectly in my 2016 VW Tiguan. It's hard to install but that's the car's fault. Be warned - these are fragile and coupled with the flexibility you'll need in your fingers to get these installed you'll have to be careful. Maybe take out the entire headlight assembly so you can see what you're doing to make it easier.Other than that, they're nice and bright and have a good white color to them without blinding other drivers. Make sure you aim your headlights properly too, especially if you're driving a truck or SUV. Don't be that person who blinds everyone and doesn't care.

This is a quality product at good price.

It's hard to choose which HID bulb replacement to get especially since there's so many at cheaper prices but this is actually an excellent choice it is made in Germany. And it's an official OEM brand. It's the real thing and not a knockoff. Fit and worked perfectly. My local auto parts store wanted $129 for their store brand bulb it was a ridiculous price. If needed I will definitely buy this exact one again for the other side.

Great price, great fit, same brand that was in it. Works just fine
