Camper trailer light wiring question

[Kaitum]

I bought a '94 Chalet A-frame pop up camper I'm rebuilding. One task is to install new exterior trailer lights (brake lights, turn signal, running lights). In looking at the existing wiring, it looks to me like they route the trailer wiring through the AC to DC power converter. Any reason for this? I was thinking of pulling the old wiring and keeping the trailer lights on a separate circuit not tied to the converter.....

I’m guessing it is to use the tow vehicle power to charge the trailer battery as well as power the AC while the trailer is attached. Then again I might be miss understanding the question. The other thing that comes to mind is when hooked up to shore power the trailer lights can run for safety/pretty in camp.

Hertervillian is correct. You could bypass it if you wanted but you'll lose some of the benefits having it run through the converter. Also if you're not going to be running it on a battery then it wouldn't matter there either.

Don't ask. Nobody understands trailer wiring! If they did somebody would've come up with a better system by now.
