Recently the right fog light fogged up and the bulb went as well. Maybe it is designed similar to the headlights to be vented and with-out the heat from the bulb it fogs? Is it a projector style bulb like headlights? I don't think it is but why the fog all of a sudden?

Actually, it fogged up while parked while the left side did not. Therefore, i guess the heat from the bulb should not affect this condition.

I did check archives but discussions were only as it relates to headlight condensation.

 

anyone replace fog light or have any condensation issues?

 

No condensation here. Or at least never noticed. But will keep an eye on it.
