For what is worth, I was able to replace the headlight bulb (the main one, not the small bulb) without removing anything.
I also have a large screen but that was no problem; once you removed the black rubber that covers the back of the bulb, you need to turn a bit the white plastic piece that supports the bulb, that's all.
Installing that white plastic piece again was a kind of pita, but you'll be able to do it with patience
