what do u mean dirty on the inside? like condensation or dirt? cause if you have dirt and trash inside means they leaking and/or car might have been flooded or underwater. sometimes condensation happens from a leak but normally they not DIRTY inside....clarify please. welcome to the club also
I have had the car since it was new, so I know it has never had any water damage or any other kind. The inside of the lense is hazy, kind of like a window inside the car will get after a while. That's the best way I can describe it. I have on occasion seen moisture inside of them after I have washed it, but it goes away pretty quickly.
