Foggy Headlights

The headlights are getting a bit foggy on my '01 S-Runner so I bought a headlight restoration kit but after re-checking my lights, it feels and looks like the foggy is happening on the inside.
I was expecting to have to polish the outside of the lenses. Am I going to have to remove the lights and take them apart to polish the insides of the lenses or is this just an illusion and the polishing is supposed to be done on the outside?
Inside or outside? That is the question.
TIA

X2. I mean you can try taking them apart but I'm not sure if you can like the 2nd gen ones? You might be better off buying some new ones.

 

x2....i had the same problem...its just moisture on the inside of the lights...nothin can really be done unless you want to replace the whole lens

 

oh sweet! thanks haha
