A friend substituted a .22 rimfire shell casing for a tail light fuse that kept blowing while towing his duck boat on a hunting trip. It turned out the cause of the problem was an intermittent short in the trailer wiring. It would have probably been a better idea if he hadn't used a live round. When the short happened the next time, it got everybody's attention when the brass got red hot and lit off the powder. Nothing like the equivalent of a good-sized firecracker going off under the dash!
