I recently had issues like this... and found I had crimped/cut my trailer hookup cable during a too sharp turn.

BTW there are really only 3 light circuits on most trailers:
A) the tail/marker circuit which is fed to both sides in back
B) the left turn/stop/flasher
C) the right turn/stop/flasher

Fastest way to check lights? Turn on the parking lights and 4-way flashers.

If an entire tail goes out --> check ground
If only stop/turn goes out --> check bulb, then socket power, then truck power
Same deal for a tail light out with working stop/turn --> bulb, socket, truck

Voltmeter can to this but so can a basic test light.

Thanks to all for the help. The dealer tested the wiring for bad grounds, loose wires, etc. and found something in the bulb, part of one of the filaments of the left 1157 bulb bridged over to the other filament without actually breaking the filament and caused a short of some type? I have the bulb and you can see the bridge.

He said in 40 years he's never seen anything like that. Also, there was an incorrect bulb in one of the left sockets. Replaced both bulbs and everything appears back to normal. Now, is there some underlying issue that caused this, don't know? I guess I'll need to watch this for a bit.

I did drop an email to Jankowski at FR, but no reply as yet.

My guess would be inexpensive, subpar import bulbs.

Yeah bulb crossing filaments is freak. Don't worry about it.

I would look at as an opportunity to upgrade to LED bulbs.
