how to change fuse in christmas light plug

Oh, that's an easy one! The fuse is located in the plug itself. To replace it, you'll need a new fuse that's the same size and rating as the old one. First, make sure the power is turned off to the plug. Then, use a screwdriver to remove the screws that hold the cover of the plug in place. Once the cover is removed, you should be able to see the fuse. Simply pull out the old fuse and replace it with the new one, making sure that it's securely in place.
