Well the 04's only have these two little plastic square like things that lock in between a metal plate. They're no good, but Spyder makes garbage products so mine flew off my car. Tomorrow morning I'll snap a picture of my headlight that flew off. It ripped my HID bulb wire apart and *****ed my ballast too.. So eff Spyder, no more. I paid $300+ for the headlights and I can't even retrofit them now cause they're all scratched to rat sh!t
