Here's a small diy I did on bf.c basically all I did was cut the sealant around the lens popped the old lens out and used some nice RTV to re seal them. The infinity ones just come right out they aren't sealed in, you either need to buy a whole set of infinity fogs and take them apart to get the lens or do so at the yard, that's what I did. The sealing method I used worked great and I have had no issues with them what so ever
