I wash my z today and know twice I put water in my head light. I think my foggy was in that head light is from the water. How could I restore the inside of them.

 

dry it out?
you have wheel well splash guards installed?

 

Yes it is installed and there is nothing wrong with with them

 

Take off headlights and reseal the outer lens with OEM sealant tape. If you don't want to use oem you can buy butyl rubber sealant which is essentially the same thing but costs less.

 

The question was if the discoloring is in side the head light how would I restore it so its clear. Would I do it the same as the out side just on the inside?

 

wtf. post a picture

 

So pull the lens off, clean it up, buy the sealant I posted and put it all back together. If the actual lens plastic is yellowing or fogged then you're SOL. However, it's almost always just the surface of the lens (either inside or out) that needs to be buffed/polished. If you need DIY directions do a search here or on google for headlight restoration.
