What causes half a string of lights to go out?
1. 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.

How do I know if my Christmas light fuse is blown?
Step 1 Blown Fuses
With the plug in hand, slide the door marked “Open” in the direction pointed by the arrow. Remove the two fuses, and inspect them by looking at them up against a bright background (such as the sky). If the fuse is good, you should see an unbroken strand of wire running between the two metal contacts .
Why do Christmas lights all go out when one bulb blows?
In this setup, when a filament within any one bulb blows out, it creates an open circuit in the wiring. As we mentioned earlier, when a circuit is incomplete, or open, electricity fails to pass through any of the wire , causing all the lights to go out.

Why are half of my Christmas lights blinking?
There are a couple of reasons your Christmas light string is flashing on and off. You have a red-tipped flasher bulb installed in a socket .

What happens when one light goes out?
If one bulb burns out in a series circuit, then this will break the circuit . This is because every device in a series circuit must work properly for the circuit to be complete. Unlike in a parallel circuit – where each light has its own circuit – so even if one bulb burns out, the remaining bulbs will still function.
