my svt does that to...the wattage is too high and it is melting the lens....this used to happen to me on my mustang. what you do is drill a pin hole size in the foglight lens from the inside out (so water doesn't get in). i haven't gotten around to it yet (i am lazy...hehehe), but this is the best fix for it that i know...good luck.
