This guy cyipher, on Blazinlow told me about this oven trick for clear corners.
I just added my own pictures of the process.

Here's his truck

Now, onto the show.

Headlight

in the oven, 350 for 5 minutes. 5 wasn't enough. Like 6 or 7. I tried with 5 minutes, but when I went to pry it apart the plastic was weakend and broke the lip on the bottom of the casing. That's ok, its the bottom. I got it out. That was 1. I did the other for 7 minutes, got it apart with less problems. But then the top half was sticking still, so I figured put it back in, but that melted part of the outer lens. That was my own fault, because it seemed I only needed to pry it, and trying to get half and bending the other half off didnt work. Pry it all around. This one didn't break.

Caution, may be hot. After its popped open, it falls out.

Here it is.

Pair of them, clear corners for free. I bought amber bulbs for them. And theres the matter of the gasket. I've heard lights with leaks have problems with humidity and such, even though there's taht pipe out, but I figured I already have the lenses off, what the hell.
So I took a knife and scraped this silver gasket seal out. I put a bead of waterproof idustrial cyanoacrylate glue in, held them with rubber bands. When it was dry I then took silicon and put a bead around the seam, and smoothed it out. Looks nice.

This concludes the oven trick.
