Default USA: How do I know what type of headlight I have?

I just got a 2005 a6 quattro and the headlights on it were really dirty and I wanted to replace them with new ones. But when I looked online most of them said that they only work on the halogen models. I didn't want to buy a headlight I couldn't use.

(And idk if it matters but I have the 4.2l if that changes anything)

You may have the bi-xenon lights. Post a pic of them. You could also try a VIN decoder site.

The 4 2L car in the USA will NOT have halogen headlights.

The number of C6 cars in the USA with halogen headlights is a tiny percentage of the population.

Aid, if your headlights are still mostly functional, find a detailer that will polish and re-coat the headlights for you.

Replacement is going to get $$$$.

As uberwgn said, just polish them, they'll look like new again. (I didn't think any of the cars for North American had halogens)

For best results you'll need to "polish" them, as in use more and more fine sandpaper to polish them clear.

Usually start with a 800, then 1000, then 1500 then after that I start using a polishing compound. Then finish with the finest polish you can buy. (tons of vids on this on YouTube.)

To figure out what headlights your car came with, look at this
