Can anyone tell me where to find a good quality HID headlight for the '06 DTS? I have a headlight assembly that is getting water inside and I plan on trying to fix it first. I'm going to pull the whole assembly out and remove everything, fill it with water, put pressure to it to find the leak, then dry it out and seal it with silicone. Don't want to pay $932 for a whole assembly (and really should change both sides if you change one). Any help would be appreciated.
