Help with my LED holiday lights.

I’ve strung together 3 sets of LED clear lights. On the first string all the lights are lit except for about the first 1/3rd of the 1st string. The rest of the lights are fine.

How should I go about trouble shooting this? I’m familiar with the old fashioned lights where either the whole string went out or a single light went out. This situation baffles me and I don’t want to spend a lot of time trying to figure it out if some doper can give me a hint.


The first string is three separate circuits–essential three strings with one set of plugs.
Because one circuit is out it means there is a break.

Make sure it’s not a fuse–these are usually in the plug.
Otherwise the likely cause is a bulb needs that needs re-seating, since a mechanical break most commonly occurs when the bulb wire doesn’t touch the contact from the wire in the string.

It doesn’t make any difference that the light itself is an LED.

If you can’t pull and replace the bulbs, try fiddling with the wires that go into each bulb holder and see if you can figure which connector is loose. Then cut those wires and connect them directly.

Just to make you feel a little better - it’s not just a problem with LEDs. Several of my dull-normal, incandescent net-light strings have exactly the same issue.
