A light bulb has come out of its socket or is half out of its socket and it has brought down the circuit. For light strings that commonly have over 50 bulbs, they are constructed in 2 or more continuous circuits. If a bulb is missing in a circuit only the bulbs in series of it will go out.
What causes part of a strand of lights to go out?

Why did half of my LED lights stop working?
Why? The heat from the LEDs will make the copper traces expand, then contract as they cool down to ambient temperature. So, if there is insufficient “heat sinking”, or “heat radiating” surface area to dissipate the LED heat, the weakest point will fracture with “stress cracks”.
How do you know which light is out on a strand of Christmas lights?
You can tell which bulb is out on your string of traditional Christmas lights by looking for the bulb that is “burned out” by looking at the tiny little filaments in the light bulbs to see which bulb is “burned out” or has lost it’s filament.

Then, take a working string of lights and plug it into the broken set. If the lights on the second strand don’t light up either, the fuse is likely the issue.
Do LED lights burn out?
Unlike incandescent light bulbs, LEDs don’t produce light using heat. This is part of what makes them so energy efficient. The downside is that their components can be sensitive to overheating, which can cause them to burn out prematurely.
Do LED lights need to be replaced?
