I thought about that but like I said, it all looks like it's on the inside. I didn't want to waist the time and money. If you look at the picture of the drivers side light look at the bottom in front of the low beam lamp. I circled an area where there are particles of something laying there. It looks like plastic particles. Now, look at the other area to the left. It looks like the plastic has deteriorated and some of it has come off. There's another larger area but you can't see it in this picture. It almost looks like the plastic has crystalized somehow.
