how do you fix led christmas lights

Well, the first step is to make sure that all the bulbs are working properly. If any of them are burned out, you'll need to replace them. Then, make sure that the wires are connected securely to the light sockets. Next, check to see if there are any broken or loose connections. Finally, you can try running the lights through a voltage tester to make sure that everything is working as it should. With a little bit of troubleshooting, you should be able to get those LED lights working again.
