How to route the lights and wires in a trailer?

How can I troubleshoot a wiring problem on my trailer?
Perhaps the most helpful thing you can do to start troubleshooting is to determine whether the problem is on the tow vehicle or on the trailer.

What to do when your trailer lights go out?

The above trailer wire diagrams don’t show the classic triple set of marker lights often appearing central on the front and back. Some requirements need them, and some do not.
