How do you change a headlight assembly on a ford crown vic?

I have a 2000 Crown Vic.... Right behind the head light under the hood.. you will see two metal, most of the time black slider things... that have a little lip that you can, with a wrench handle, pry up using a little leverage... They are to hold the head light tight in place so it doesn't wiggle.... after that disconnect the wires and pull it out.
