I took apart a sign I made a few years ago and wanted to save the lights I installed. I noticed there was a slight burn mark. Any ideas here? This is a "factory" joint, not something I soldered. Is this burn dangerous? Should I discard it and replace? It's interesting that the rest of the lights are ok, just the joint is burned.

Is it an electrical hot spot, or did it discolor because of the heat of the soldering iron? Was it there when you installed it?
I'd probably trash it because even if it is safe to reuse, I probably wouldn't be able to find it again when the opportunity arose.

In order to cause that burn, it would have had much more current running through it than those LEDs could possibly draw. Possibilities include either a short (likely) or another 30 or 40 meters of LED strips! (each 10 meter/300 LED strip draws 2A)
If all the lights work and the joint does not get hot, then it should be fine if you don't repeat the prior infraction.

That is where the factory soldered the LED strips together for the required amount of LED's.
It's no problem at all, just a bit more heat during soldering. Hard to say, but that might also be flux, did you hit it with some alcohol to see if it comes off?

John,
It's underneath some type of silicon protective barrier.
Just use them, there's nothing wrong other than a little cosmetics.
