how to change a fuse in christmas tree lights

Changing a fuse in Christmas tree lights is relatively simple. First, unplug the tree from the wall outlet. Then, locate the fuse box on the back of the tree. Carefully remove the fuse and replace it with a new one. Once you've replaced the fuse, plug the tree back into the outlet and check to see if the lights are working properly. If not, repeat the steps until the lights are functioning properly.
