how to test led christmas lights

Testing LED Christmas lights is a fairly simple process. First, ensure that the lights are unplugged and disconnected from any power source. Then, inspect the lights for any visible damage or defects. Next, test each bulb or light strand individually to ensure that each one is working properly. Finally, plug the lights back in and turn them on to verify that they are functioning correctly. If any of the lights are not working properly, it is recommended to replace them.
