Why is my string of lights not working?
The problem may also be a bad fuse. Most string lights have two tiny fuses inside the plug. Typically, a box of lights is also packaged with a replacement fuse or two. Then gently pop out the fuse and replace it with new ones.
Why do LED string lights have 3 wires?
A: The usual reason for three wires is to carry though a live and a neutral wire to a socket at the far end of the string, into which another string may be joined. If you join two such strings in series, they will be dim, because each string (usually of 50 lights, sometimes less) is activated by line voltage of 120V.
Why is one of my LED light strips not working?
Bad Pin Connection – If your LED strip light fails to turn on at all, then check your pin connections. Most likely, the pin is not inserted correctly. In rare cases, the pin is faulty. If your RGB strip lights won’t change colors try flipping your strip light around and reconnecting it.
How do 3 wire LED lights work?
The string of light is designed to daisy chain. The end of one can plug into the start of the next one. The lights are in series between the neutral at one end and the hot at the other end. Thus three wires – hot, neutral, and the series lights.
Can I cut 3-wire Christmas lights?
Short Answer: No, you can’t lengthen or shorten standard series-wired incandescent and LED Christmas tree light strings that are made with 2 or 3-wire harnesses. Even if they work at first, they won’t last long.
How do you fix parallel Christmas lights?
Troubleshooting steps if a light wired in parallel goes out: Check the fuse and replace it if it is blow. Reduce the number of bulbs or length of light string before plugging into an outlet if the fuse has been blown. If you make adjustments and the fuse blows again, then there may be a break in the wiring.
How to fix a string of lights that won’t turn on?
The only way to fix the problem is to find the bad bulb. Sometimes only a section of the lights will go out, making your job pretty easy. However, if the entire string of lights is out, you will need to check every lightbulb. That means pulling off each bulb, replacing it with a good bulb, and plugging it in. If it turns on, you found the bad bulb.

How to fix led Christmas light bulbs that won’t turn on?
You have to take every bulb out, look into the terminal, and see if it has corroded in any way. You can usually clean the corrosion away with a small file or brush and get the bulb working again. Sometimes, the LED Christmas light bulbs just get a little lose, and the strand of lights stops working because the bulb isn’t adjusted right.
Can I repair a broken string light shunt?
Even if you can repair the shunt and get your string lights working again, you should still replace any bad bulbs as soon as you can. If your string light set is wired in series (as many are), one burned-out light bulb can make your entire light string go dark. To fix the problem, you’ll need to follow the circuit to figure out where it is broken.
