Sorry for being such a newbie. I want to change out the interior incandescent light bulbs for LEDs. But Mr. "Dim Bulb" can't seem to get the bulb covers off of my interior light fixtures. I figured it was the typical squeeze and pull method, but that didn't work and I don't want to break the covers in the process. It's a 2011 Gulf Stream AmeriLite 15FDLE. Any ideas on what I am doing wrong?
