Almost all of our F150 have no trouble running these fog units, but occasionally we have had reports of a blown fuse. This can be caused by a variance of things, sometimes not directly related to our bulbs although the bulb(s) can be shot if the fuse breaks. If you experience this issue and are confident the fog lights are at fault, you may need to install an inline resistor to help limit the peak of electrical charge running across the fuse.
Blown a fuse with a fog unit?
