I'm having a little problem with some new foglight bulbs I purchased. They are stock wattage but for some reason after I installed them, I keep blowing the fuse. I put the old bulbs back in and they turn on. The new ones work as well, I hooked them up direct to the battery and they turn on. But once I put them in the housing and connect everything, they automatically blow the fuse when I turn the lights on. What could be the problem?
