how to fix christmas lights on tree

To fix the lights on your Christmas tree, you'll need to first check the cord for any breaks or frays. If you find any, replace the cord or repair the damage. If the cord is fine, make sure that the lights are plugged in and that there are no loose connections. If the lights still don't work, try replacing the bulbs or fuses. Be sure to turn the power off before making any repairs or replacements.
