The fuse or the fuse clip are not split.The tension clip that you see is right where it is supposed to be. The fuse blade was not inserted into the fuse clip, but instead, the blade was placed below the fuse clip..The lower part of the fuse clip has darkened from overheating but it is still intact.
Maybe this disconnect takes care of the lighting and the installer didn't have a flashlight with him at the time of install [Linked Image]
