    I have four strings of LED lights on my tree, 70 lamps per string, three string wire.

    Two of the strings have 1/3 or so of the lamps out on each. The point where the working bulbs stop and the dead ones start is a component of some sort that is inline with one of the three wires. It is about 2 inches long, round and enclosed in a plastic case with a wire at each end. The plugs on each string have two fuses in them and have been tested good with my DMM. What is in this pod and how should go about troubleshooting these strings?

    Thanks and Merry Christmas!

    Bust one open and see. Maybe a filter, or maybe where you can join strings together, maybe it makes them flash or twinkle.

    Youtube has lots of videos, maybe one of them will help.

    Thanks Lloyd, but these are in the middle of the string (two per string) and are sealed. The lights are not flash or wink lights.

    Hey Lloyd, you da' man!

    I watched one of the Utube videos and saw how to fix them. You do need a LED bulb tester to find the bad bulb, and that is the problem here.

    The "pod" is actually a rectifier because LED Christmas tree light strings run on DC, not AC to avoid flickering. I think this may be the same issue that affects LEDs in old Bally/Stern machine where you have to change the Lamp Driver board when installing LEDs. Or not.

    Thanks again, Lloyd.

    They do make light testers a special tool have wore them out before This is why i still do the tree with incandescent lights still. Been fixing them so long its like an old bike jump on and go. Had some led sets flickered too much and once they broke to the scrap bucket they went at 15$ each was kinda pissed have paid under 2$ for the others and getting on average 5 to 10 years out of them found some this year that 19 yrs old this year. I'll go snap picture then get it on the computer for all to see.

    The elves are trimming Santa’s Christmas Tree. 1/2 the tree has red lights, 1/3 has blue lights and 2/5 must have green lights.

    What is the total amount of lights needed for the tree?

    Ok got the picture yes it gets warm. lights or spread over 3 different cords to keep for starting a fire by overloading cord. care to guess the number of lights. lets just say i keep a pre made spread sheet to pull it off. Added 42 bubble lights after the photo the light you see is the light off the tree no flash.

    The tester is a light keeper pro the red version is for incandescent lights and the yellow is for led sets.
