how do you get to the bulb in the corner lights to change it out?

I'm not in front of the stang right now but the first thing you need to do is take that big black plastic cover out of there. I'm talking about the cover on top of the radiator. It also blocks the access to those corner lights. Then you'll see the bolt/bolts (not sure..) that holds the corner light. Then tap it a little bit to take it out.
