Anyone have to replace a foglight?

I saw a video for a Mazda 3 and it looked simple, but for the 5, maybe not so much. Looks like I have to take apart part of the fender well, etc. Hardest part is access, tough to get under the car.

Wondering if the black trim pieces from around the light itself can pop off? Would this allow for easy access? Any advice? (2008-Mazda 5)
