Foglights failed to work for a short while...

[skeck]

My foglights failed to work this early evening after never having a problem since their install a month ago. Then about ten mnutes ago they came on after I had the switch on for a minute, they just suddenly came back on. It rained today so i am wondering if possibly something got wet and caused this? I checked the lenses themselves and there was zero condensation inside, so they are sealed. Next thought is to check where the wires go into the back of the lights to ensure it is sealed tight enough where the connection is. The dash light was still coming on for the fogs even when they weren't working, so i am assuming it is not the connection anywhere but where the lights connect themselves, but what do i know. Anyone have any ideas for what may be causing this or how I could verify? Thanks in advance for any advice you can offer.
