Changed from the stock 35w foglights and put in some 50w bulbs, they worked for a short while, then blew fuse. Changed fuse and blew again. I figured the stock fuse and wiring could/should handle 50w bulbs? I bought the bulbs from autozone, so maybe the bulbs are higher wattage then the package says?
Is your fog light fuse a 15A?
I would worry more about heat, unplug one of the fog lights and turn the remaining one on, wait a few min. then check fog light lens temperature.94
