- Make sure all plugs are connected that are in the Christmas Tree
- Check the circuit breaker first.
- Plug the lights into an electrical outlet.
- Turn the light switch and the circuit breaker on.
- Check the fuse or fuses from the plug at the end of the light strand (usually the glass-cylinder type with a wire filament). Use a small screwdriver to pop out the tab and open the plug. If the fuse is charred or burned out, replace it with a new fuse, and plug the light strand in your outlet.
- If the fuse isn’t the problem, there’s a problem with a bulb. Untangle all your string lights, and check for loose or frayed wires, damaged sockets or broken bulbs. Discard any damaged string lights
- Replace any damaged bulbs with spare ones. Make sure to use bulbs with the same voltage rating as the rest of your string lights.
- Once you find the faulty bulb, unplug the light strand from the outlet, and replace it with the new bulb. Firmly seat each bulb in its socket.
