i do not understand this... i nthe past 2 weeks i've recieve brand new bumper lights and headlights, i put both sets on and the day after they were all fogged up... my fukin new 250 dollar headlights i put on last nite were completely fogged up this morning.... i honestly dont understand what the heck is going on .....its frusterating the hell outa me, its emberessing to drive around like that

 

Prolly since it was cold, moisture accumulated in the headlight housing. Use some air to blow as much of it together so it can be removed from the headlight. When that would happen with my explorer (well I drilled holes in the housing) I would just leave my brights on and let the heat move the water. The car was hooked up to a battery charger just not to kill the battery. You might have some seams that aren't sealed hence the water entrance.
