So I bought a replacement bulb for my 05 fog light. I removed the plastic under the bumper, twisted off the black cap on the back of the fog light and it revealed the wires for the fog light. The problem I am having is that I am hitting some large black plastic box and cannot get the black cap out of the way and I also cannot see the back of the fog light to get at the retaining wire that holds the bulb in.

Any tricks on replacing these bulbs? I can see some large screws under the fog light assembly but it look like they are attached to the bumper and I don’t see any benefit to removing them. Although I could be wrong. I understand the process; I just can’t get the black cap out OR see the bulb itself. Thanks!
