how to replace the fuse on christmas lights

If one of your strands of Christmas lights stops working, it's likely due to a blown fuse. To replace the fuse, you'll need to follow these steps: 1. Turn off the power supply to the lights. 2. Locate the blown fuse. It will be in a small plastic housing with a glass bulb inside. 3. Remove the old fuse and replace it with a new one that is of the same voltage and amperage. 4. Reconnect the power supply and test the lights. If the lights still don't work, there may be another issue with the strand.
