The headlights on my 2011 Dakota look brand new, but they keep fogging up. Is there anything I can do to fix them? Any help is much appreciated.

 

If your fog lights are fogging up condensation is getting in them. My brothers neon has a crack right on the lenses and does this. You said yours look new but there could be a crack somewhere on the housing instead of the lens. Id pull it out and check.

 

+1. Has to be getting in there somehow, crack or damage to the lenses is most likely culprit if the bulbs are screwed in tightly.

 

If the unit doesn't appear to have any defects in it, drill a 1/8" hole in the lowest point of the bottom, NOT THE FRONT. If you're worried about anything getting in the hole, drill it at a slight angle leaning back at the bottom.
The hole will allow it to breathe.
