interior trailer lights

I tow an enclosed car trailer. These interior trailer lights only work if the ignition is turned on. Is there a simple way to make the lights work without the key on?

The lights in the trailer are most Lilly wired into the AUX circuit on the 7-way trailer plug. This plug is only powered when the key is on. You could either require your truck so that circuit is live all the time ( and you run the risk of having one of those lights left on and killing the thick batteries). Or install a 12V battery on the trailer to run the lights when the truck is off. It will get recharged when the truck is on.

So if I tee into the aux wire on the plug side (trailer) and run that wire to the + side of a battery mounted on the trailer and run a ground wire from the - to the frame of the trailer the lights should work no matter what and when the truck is hooked up it will charge the battery? Do I have this right?

Yep. Make sure you have power from the truck to recharge the battery an you'll be good.

My enclosed trailer inside lights are hooked into the tail light circuit. With this setup, if your parking lights are on (not the headlights), then you have power to the inside lights available. This setup works for me, as generally I don't need the interior lights to be on for long periods of time.
