Been there done that and they worked great with new HID bulbs and ballasts. However, when you go to install them you have to grind off some tabs and what we did not understand was that you have to be sure that the seal is still intact around the lens when you grind. It looked good to us.
Evidently we did not get it sealed on either one as along came a spider and built its web in the drivers side and passenger side just has a lot of dust in it now. HID's are far better, BUT
Jim Nichols just recently replaced his and installed LED bulbs. My next set this year will be LED's like Jims and also making sure to get lexel all the way around the seal area. Jim made a point about this part of the replacement when I saw him in Quartzsite. Jim indicated they are marvelously better.
There are many places to get other than Lincoln, ebay, amazon etc.
