The current draw of high-output bulbs is more than the factory wires can handle and will result in a fire. The more thermally stable fuse is typically filled with sand in order to prevent the conductive film from forming. Jefferson operates Red Dirt Rodz, his personal garage studio, where all of his magazine articles and tech videos are produced.
