Lately it has been -15 C for a few weeks now. Today it has gone up to -2C, mabye close to 0C in some areas where I live.

I noticed fogginess and small condensation inside the tail lights on the clear plastic shell. Obviously I cannot wipe it off, its all inside.

Last fall, when I was my car with powered water jets and soap, I noticed everytime small amounts of soapy water running along the black well base inside the perimeter of the tail light. So it's inside and at the bottom only...where water likes to go. However it is very little amounts and it seems to drain away.

Is the fogginess normal inside a tail light? Is it normal to have some moisture inside any of the lights??

What is your opinion? thx
