Has anyone seen this before? Looks like condensation on the inside of the headlight assembly. Right? Wet sanding the outer surface wouldn't help.. From what I can tell.

 

I know it on the inside but here's a thread and YouTube video on how to do the outside and clearing the haze. I know you can cook the headlight to open them up and clean them as well.

I've opened up several sets of 3000GT/Stealth headlights with the oven method. I'm sure the G headlight wouldn't be much different. It's been several years since I did a set but I believe I used 250* for 5 minutes to get it started. The glue started setting again and I put it back in for another 5 minutes and popped the cover the rest of the way off.

 

Yeah if its not sealed then the moisture can get trapped in there. You have two options, open them up and clean them very well (upgrade the lens while you're in there haha) or replace the whole headlight.

 

I opened mine, the only thing I noticed was these headlights are huge!! It just barely fits in my oven without touching anything. I think I did 250 for 7-8 minutes and like stealthee said, you can get it started or if you're really fast you can probably open it. If it gets stiff, put it back in there for a few minutes. Just be patient.
