White and red are one piece, it's 3 8mm nuts and it comes out. I left one in the oven for 45 minutes just to see if anything went wrong and it was fine, only the glue gets soft. It's a nasty glue. You're trying to open them so the orange plastic thing can come out, there's a bead of this white glue crap around the whole inside perimeter of the light, you have to get that melted so you can pry the light open, and make the reflector come out after you've already loosened it with a pen or something,
this is the reflector, notice on the right side there's two little tabs, you need to pop those out so it rattles around, that's why you poke a pen in the hole where the turn bulb was.
I had an extra tail housing, so Here's the actual housing, there's three screws that will have nuts on them that you get to from the trunk(marked with green), you can see the orange reflector through the hole, and it's two tabs that you need to get loose with a pen or whatever, then in yellow I marked two of the tabs(there's like 2 on top and three on the bottom) that have to be lifted so you can pry the housing open, you need two big flat tips scewdrivers, you start prying the housing, then lift the first tab, get the housing open some more then the second tab, so on and so fourth. This isn't the easiest thing to do, and procede at your own risk, like I said I cracked my first attempt, it's only a little 1/4" crack but it wasn't easy.
