A diode is probably your easiest solution if you don't mind the voltage drop inherent with them.I need a resistor, relay, or diode that will only let 12V power travel one direction.

This does look like a good solution if the dual battery charging is OP's application.It is called a VSR.. voltage sensitive relay
or for USPPT Voltage Sensitive Split Charge Relay - 12V 140A
12V 140A voltage-sensitive relay from Portable Power Technology for 2-way split charge applications in camper vans, motorhomes, 4x4s, boats etc.www.12voltplanet.co.uk

See if this video helps you any:Looking to put several lights on one switch in one location (in Jeep) but still be able to switch individual at another on trailer.

Thanks, little deeper explanation of my situation. I have three sets of KC C-Series lights on my DIY camp trailer. I want to run them separately at the Trailer control panel, but run them together on one switch in the tent, so encase something happens during the night I can “light up camp”.See if this video helps you any:Looking to put several lights on one switch in one location (in Jeep) but still be able to switch individual at another on trailer.
I monkey around with diodes quite a bit so don't hesitate to let me know if I can help further. One main consideration is to be sure to use diodes with enough current capacity. Also, some diodes will reduce the voltage more than others. Schottky diodes may be a good choice because their voltage drop is often less than a standard diode.

The lights are currently just fused and switched, no relays, and I’ll be running a wire.Got it. I like the way you think!
Give me a bit to figure out the best way to get you a wiring diagram. But for now, is it safe to assume that the trailer lights are operated via relays and not straight from a switch? Also, are you going to run a wire into the tent or will you have a wireless remote?

Do you know what amp rating the lights are? It's easy to exceed the rating of the switch with a few lights. What model are the lights?The lights are currently just fused and switched, no relays, and I’ll be running a wire.

Don't forget that he still needs the 3 trailer switches to work independently. If I understand you, you'll be tying those three together when you gang them together for the other switch. Right?You need one relay per switched circuit. The switch in the tent will control a relay that will control the rest of the relays bypassing the the other switches.

The only thing I do t like about diodes... if they fail in the trail, then no where to get new ones very easily... relays are sold almost every where.Do you know what amp rating the lights are? It's easy to exceed the rating of the switch with a few lights. What model are the lights?
I crudely put this together before I saw your answer and I assumed you'd be using relays. See if you can follow it. I'll work on making another without relays.
In this diagram if two lines cross, but there is no dot at the intersection, there is no connection.
Again, I drew this with the assumption you presently had one relay per circuit:

Yes... gang the three with one, so a total of 4 relays.Don't forget that he still needs the 3 trailer switches to work independently. If I understand you, you'll be tying those three together when you gang them together for the other switch. Right?

And that will cause any of the 3 trailer switches to activate all 3 circuits.Yes... gang the three with one, so a total of 4 relays.

How many on each switch?I’ll wire it which ever way I need to, to be safe, and get the desired results. Here are the lights I’m using.
