I just removed the 6000k low beam/large halo rings from my car, as I got a set of 8000k to replace them, and now my low beam rings will finally match my high beam rings. I removed the 6000k rings no problem and they work fine - they have a little adhesive residue on them, but they light up no problem. They were only in my car for about a month, and AAC says they should last like a million years, so I figured I'd offer them for-sale for anyone who wants spares or replacements. They are 2 6000k outer/larger/low beam halos for the 300c. I'm asking $20 shipped for 1 within the US, or $30 shipped for both within the US, or whatever you guys deem is a fair price. Thanks!
