2005 FX4 Foglamp Bulb Prob
 

I recently replaced the exploded foglmap bulb on my 2005. Once replaced,the lamps worked for about a half hour before the new bulb exploded as well. I've not had any electrical problems with the truck and don't know if this is a fluke or something internal. Any help or suggestions would be appreicated.

It exploded? It probably was hot (normal after being on for awhile) and then it got wet. Any sign of water inside the housing?
