Unplug the Christmas tree lights and locate the fuse panel. The fuse panel is located on the accessory plug with two prongs, commonly known as the male plug.

Use a small flat head screwdriver to slide the fuse panel cover open or to slide the fuse panel drawer out. - 3). Turn the attachment plug over to remove the fuses from the Christmas tree lights. In most cases, the fuses will just fall out into your hand. If they do not, tap the plug gently against your hand. If the fuses are stubborn and still won't come out, it may be necessary to gently pry them out with a small screwdriver or knife.

After replacing fuses, close the fuse panel completely.
Determine if the fuses on the Christmas tree lights are blown by holding them up towards a light and looking closely at both fuses. If one or both of the fuses appear to be dark or black, the fuse is probably blown. If you're just not certain, you can use a fuse tester to test the fuses. Replace the blown fuse with a new fuse and insert them back into the fuse panel, securely closing the cover back in place. Plug in the Christmas tree lights to ensure they are now working.
