how to fix christmas tree lights on prelit tree

If you have a prelit tree, the first step is to make sure the lights are plugged in and the switch is turned on. If the lights still don't work, then check the fuse box and replace any blown fuses. If the lights are still not working, it's possible that the lights have burned out or there's an electrical issue. In this case, it's best to hire a professional to troubleshoot the issue.
