Introduction |
| In this guide, you will learn how to replace the fuse on a pre-lit incandescent (non-LED) Christmas tree. Incandescent lights are electric lights that have wire filaments that are heated until they glow. The filament is enclosed in a glass bulb that protects the filament from oxidation. | | | After using this guide, your Christmas tree should light up again. Be sure to unplug the tree from power while removing the fuse and use extra caution when handling the fuse, as it can be fragile. | | | Before beginning this guide, make sure you know how to use a continuity tester properly, and that you know how to read it. In addition, be sure that double check that you have unplugged the tree from power and do not have any liquids near you while working. Liquids and anything not needed for this fix pose a hazard that can be very dangerous to you. |
