How do you fix a tangled string of Christmas lights?
Unravel the entire strand of lights. Do this in a space where you have plenty of room where the lights do not become tangled again while you work. It sometimes works best to sit down and begin by working on each light, one at a time, pulling them across your lap as you work.
Can you repair Christmas lights that are burnt out?
Christmas lights are a real nuisance to repair. The hard part is finding the bulb that is burnt out and most people do this by trial and error. If you have a string of LED lights that are of the non-replaceable type you may think all is lost. But don't be too hasty. What if you could find the problem LED and then repair the string.
How do you fix LED lights that are not working?
The fist step is to find the LED that is no longer working. The non working LED will obviously be in the string half that is not working. With the lights plugged in, use the voltage detector to check the live voltage wire between each light, starting at the end that plugs into the wall outlet.
Why are LED lights wired in series?
It's interesting- pairs of LED's are in parallel and these pairs are wired in series. The string uses a full-wave rectifier (improves flicker) and splits the diodes between the plug end and receptacle end (so both plug and receptacle are not too large). So for an extra wire per bulb this design gains redundancy- one bulb...

Why are there 3 wires on LED Christmas lights?

Can you cut LED string lights and still work?
Will they continue to work if they are trimmed down? Yes, LED strip lights will carry on working after they've been cut as long as you cut along the designated lines. LED strips are made up of several individual circuits, so each cut line demarcates the end of one circuit and the start of a new one.

What happens if an LED is wired in backwards?
1) Polarity Matters LEDs, being diodes, will only allow current to flow in one direction. And when there's no current-flow, there's no light. Luckily, this also means that you can't break an LED by plugging it in backwards. Rather, it just won't work.

How are modern 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. The lights provide a resistance when a voltage is applied which passes current to each light bulb.
Do LED Christmas lights have shunts?
If an LED fails, there is no shunt. However, the whole string of lights continues to work. A failed bulb simply shorts out, creating a path of less resistance. The current can travel through the dead LED and into the other bulbs.
How are strings of Christmas lights wired?
Many strings of Christmas lights are wired in a series. The current from the outlet when the string is plugged in travels down the wire to the first light. Then, it continues from a wire on the other side of that light and on to the second and so on until it reaches the last light in the string.
Can you replace a burned out LED bulb?
So as far as repairing it seems best to replace burned out bulbs immediately. This is because if the other bulb paired with a burned out bulb goes then the entire string goes. Then tracing which bulb is bad requires special effort. Of course I've read that sometimes LED bulbs fail shorted instead of open. So this helps.
Can series strings be daisy chained?
Typically one of the wires would be parts of the series string and the other two would be connected to each side of the power. That allows sets of series strings to be daisy-chained. Below diagram from here:
How to get rid of a tangled light?

What is a mini Christmas light?
Basic mini Christmas lights are typically three-wire strands. For families intending to use the Christmas lights year after year, troubleshooting these lights may be necessary. When an entire string of lights stops working or a section stops working, it's important to troubleshoot the issue in order to get the lights working again. Advertisement.
How many lights can you string together at one time?
Never string together more than three strands of lights at one time to avoid blowing the fuses.
How to check voltage between lights?
With the lights plugged in, use the voltage detector to check the live voltage wire between each light, starting at the end that plugs into the wall outlet. There should be voltage detected at the live wire going into the first light. Then check the wire that goes from the first light to second light.
What is your fault if you burn yourself with solder?

Do LED lights have a resistor?
LED's do not like a lot of current so besides the LED there is also a current limiting resistor in each light. For this repair we are actually going to bypass the faulty light. This will increase the current that goes through the remaining lights because we have eliminated part of the resistance. However, taking one light out should not increase ...
How to splice wires unplugged?
Unplugged, you touch one probe to a wire at the beginning, and the other probe to the ends , until you find which one has continuity, use different colored tape to "flag" these pairs, then you do your splicing as planned , matching the wires to each other as they were arranged at the plug ends.
