How can I fix Christmas lights without a tester?
Pull out one bulb at a time, and stick a piece of folded up foil into the bulb socket. If the lights come on, you know that’s the bad bulb. If they don’t, put the bulb back in and move on to the next one.
How do you know which bulb is out on Christmas lights?
The easiest way to find faulty bulbs on incandescent Christmas lights is with a Christmas light tester. Simply bring the light tester close to each bulb. The tester’s indicator will light up when it’s near a functioning bulb.
Why does half a string of lights 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.
Why are half of my LED lights not working?
If half your LEDs are not working, it means that there are 2 strings of LEDs wired together in parallel – each parallel string has LEDs in series. You likely have a broken wire, or an LED bulb is broken or out of the socket.
What kind of fuse do Christmas lights use?
Incandescent Mini Light Sets use 3 amp fuses. Heavy Duty light sets 5V use 3 amp fuses. C7, C9 light sets use 5 amp fuses. G40, G50 light sets use 5 amp fuses.

How are Christmas lights wired?
The lights are wired in series from the first to the last light. The path of the electric current flows through the circuit from the source and back around a single wire. When the voltage is applied, current flows directly to each light bulb from the source. Christmas lights arranged in a parallel circuit.
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.

Do pre lit Christmas trees have fuses?
Most prelit trees have fuses inside the electrical plugs. Double-check that the tree is unplugged from the wall and then check each plug and connector for a blown fuse. Slide open each plug to remove and check the fuse. Put the new fuse, often included with the tree, into the plug.
