Individual lights usually stop functioning for one of two reasons: they’re loose or they’re burnt out. When bulbs loosen from the string, they may disconnect from their housing. All you’ll have to do in that case is tighten them a little bit. They should turn back on as soon as they’re housed properly.

Why do Christmas lights have 2 fuses?
Typically, these strings of lights have two tiny fuses, one in each side of the AC line, located inside the AC plug. The fuses are intended to melt or “blow” before the copper wires in the string could melt or cause a fire from overload. Sometimes the instructions with the lights say, for example: “DO NOT OVERLOAD.
How long do Christmas lights last?

What do burned out Christmas lights look like?
The inside of the bulb will be a little blackened. Normally, if a bulb is just burned out, the rest of the lights will stay lit unless a tiny little wire that looks like a little hair at the base of the bulb has also lost connection. If that’s the case, stop using the string of lights and replace it with a new string.
What causes a whole string of lights to burn out?
Often a single bad bulb will cause a whole section of a strand to go out because they are in series. One open circuit (bad bulb) will stop current flow through the whole section of the string. There is a different type of bulb that has a shunt wire in it.
How do you troubleshoot 3 wire Christmas lights?
Unplug the lights. Locate the tiny fuses (there should be two: one on each side of the AC line, inside the AC plug).

The corrosion that builds up inside the outlet makes them more prone to tripping.

“Brittle or exposed wire indicates that your incandescent string lights are past their prime and potentially unsafe to use,” says John Banta, a CR test engineer. If the wire is pliable, plug the strand in to test the bulbs. If a few bulbs are out and you have the original spares, it’s safe to replace them.
