Help me understand this

Strange, to say the least! :-(

Sounds like enameled wire

I’ve been at this a long time, but leds and wiring are not a strong suit.  I purchased a plasticville signal bridge. I had someone put led lights in it and I’m busy getting ready to wire it up.

What I don’t understand is it appears that he used copper non insulated wires for common and anode.  They are all wrapped up together but don’t short when power is applied. I don’t understand how that works.  

Why not contact the person who did the wiring and ask him???

Can you ask the guy that wired them for you?....that looks like a hot mess,....

That's ugly, I think Pat said it best.

That's what it looks like.

The wires should be fine if you don't kink them against each other a lot. They are insulated.

Magnet wire

Magnet wire or enameled wire is a copper or aluminium wire coated with a very thin layer of insulation. It is used in the construction of transformers, inductors, motors, generators, speakers, hard disk head actuators, electromagnets, electric guitar pickups and other applications that require tight coils of insulated wire.

He labeled them for you. Did you specify the operating voltage you wanted? Looks like he added resistors for that voltage.
