I've watched this to see if anyone had any ideas on why the led was lit.
Non-electrician here, but, I like to think I understand power.
Bottom line, somehow that one led is getting enough power to light up. Where is that power coming from? I have seen a couple of reports that talk about "hot skin" and how dangerous that can be. Could your rig have a small short somewhere that is leaking enough current that is getting into the water you mention to power up the light? Or is this really not worth worrying about?
Inquiring minds need to know!
