Does anyone know how built in Christmas tree lights work?

Ok here’s the top of my tree. It has built in lights. About half the top works. The other half doesn’t.

Most of the lights look like this one.

But some look like this.

One of the bigger ones (second type) when I removed it the whole strand went out. So I figured the others that were like that also controlled a bunch of lights. But they don’t seem to.

Does anyone have any ideas for me? I am at my wits end.

Feel free to ask questions I might be as clear as I think I am being.

Is it plugged in? Sometimes the connections get loose.

Fuse? Sometimes there are little fuses by the plug.

I’ve been looking for fuses and don’t see any. But yes I had that thought too.

Do you have a multimeter?

Do you know how electricity works?

Do you understand series and parallel circuitry?

No.

Enough to be dangerous.

No.

That’s a tired joke. Definitely not worth 3 points.

Says the guy who provided multi-year updates

Deduct three points

Welp, then you’re screwed. Throw it out and buy new.

Or, preferably, get a real tree - unsure how anyone can think it to be Christmas without the smell of a real tree. But that’s a whole other discussion…

As for troubleshooting your lights: if you don’t have basic knowledge of series and parallel circuits, you don’t really know how electricity works. I could give a quick explainer, but without a meter to test as you go, the info would be meaningless to you.

Simply replacing bulbs is a shot in the dark (from what I think I’ve been told about LED lights like these).

Probably the easiest thing (other than the new tree scenerio) is just to buy some lighting strands and string them the old fashioned way.

Or as I suggested…Candles

Candles are for birthday cakes, not trees.

Might as well light the house on fire and cut out the middleman…

I have electric lights that work though!

That’s… a strange flex.

But yay! I guess…?

It made putting up my tree easier

He doesn’t need a multimeter. Just tell him to lick it like you do a 9 volt battery.

I found a website with troubleshooting tips. It doesn’t sound like rocket science. I have tried all of their suggestion except for changing the fuse on that strand.

I just need to figure out where the hell the fuse is.

On my parents set as a kid it was one of the bulb sockets but instead of a bulb it was a fuse

And now some of the pre lit stuff has a fused bulb…

@BLeP look for a bulb that has a different colored base (grey) or find a socket that doesn’t have a bulb but a fuse holder. That should be your first stop.

If you can’t find one of those, find the first burnt out bulb on the string and try replacing it.
