All I know is when I put my new clear headlights on, I ended up ripping my stock ones off with brute force. The little plates on the back side screw on and off, but they are a b*tch to work with, so I used needle nose pliers to break the damn things off and pulled hard after unplugging the connector. Then my new ones just popped in. You have to take the corners off, which is one nut on the back side of the corner light, and then they just pop out as well. Sorry, Im not very specific, but I didnt really think about it real hard cause it was 30 degrees outside here in Iowa when I was doing mine!
