Whats up! I just bought an 05 Navigator and comming from a history of dropping and performance upgrades its definately a nice change. My first upgrade i have in mind is swapping out my halogens to hid's. Now i know i can buy a kit for my headlight but i want to do it right so i searched out a set of headlights from and HID stocked Navi (proper reflector setup) and depending on the color of the factory bulb i would like to upgrade to 6K. I searched this forum and couldn't get a specific answer so my question would be besides purchasing a set of harness from my local lincoln stealership ($190, so if any one knows of a better deal please let me know) what else is needed to make the conversion?
