Installation - some strings don´t work

I have installed 5 Sting Lights (5x5 mtr). I tested them initially and everything worked. After installing them, only - the 1. ,2. and 3rd string works. The last lamp in the 3rd string flashes. I’ve tried replacing the last 3 strings with a new one (which works), but to no avail :cry:
Is there something I’m overlooking?
Anyone who can help?

Hi John, welcome to the forum!

I guess you mean string lights, right?
It’s difficult to help you when you give no details about those lights and how you integrated them.

Someone could probably help if you gave us some information. What they are, how they are connected, what hardware etc. etc.

But my guess is they aren’t connected properly :slight_smile:
