Brakes light up in the front

That was one of the first things I checked. Bulbs are the correct numbers and in there properly. Not sure how I'd test to see if the sockets are messed up.

Regarding the turn signal assembly, once I have it to the point seen in the photo how do I then remove it? I took off the 3 screws in the center and the 1 longer one that holds the switch handle on. The plastic piece moves and wiggles, but does not seem to pull free. I don't want to yank at it and risk breaking something.
