Most modern Christmas light sets come equipped with tiny fuses housed within the plug. If your entire string stops working, the fuse is likely to blame. Begin by unplugging the lights. Locate the fuse compartment, which is usually a small sliding door or trap on the plug itself. Open it using a small flat screwdriver or your fingernail. Gently remove the blown fuse—often glass cylinders less than an inch long—and replace it with a new one of identical rating, typically included with your light set. Secure the compartment, plug the lights back in, and watch for that holiday glow to return.Tips 1:As a designer, I see moments like these as an opportunity for intentional improvement.
