To the OP - in your original post you said your employer has a 24' travel trailer you'd like to use for a trade show and have the exterior lights on it flash to attract attention to your display. The solution is simple - if the trailer isn't already equipped with a battery (which it should be in order to tow it anywhere anyway) install a basic Group 24 deep cycle battery on the trailer tongue, connecting it properly so the positive cable is connected to the battery positive terminal and the negative cable to the negative ... now Pin 4 on the trailer's Bargman connector will have + 12.6 vdc, Pin 1 will be negative. The negative side of this 12 vdc system is already hard wired to the trailer's lights so in order to have the exterior lights come on all you have to do is connect Pin 4 on the Bargman connector (your + 12 volt source) to Pin 3 on the connector which is the positive side of the trailer's exterior lights.
If you use a short length of wire or a flat fuse to do this then the lights will simply come on and remain on but if you instead use a flasher the lights will flash on and off, just as you had asked in your original post. Just go to any automotive supply store and ask for a heavy duty flasher ... if you'd rather not install it in a box with a fuse and switch as I did then just bend the pins so you can simply plug the flasher directly into Pins 3 & 4 of the Bargman connector and as long as it's inserted the lights will flash. To stop the lights flashing just remove the flasher.

Try this.
Go to the auto parts store and ask a counter guy or get on Amazon.com and order an EL12 flasher unit.
E12 flasher unit
Now drive to the trailer and plug the trailer into the wall outlet or the generator.
Plug the flasher unit into slots 4 and 3 on the trailer plug.
See if the lights flash.
Unplug the flasher unit to stop the lights flashing.
If the lights don't flash you need to find a way to hook a fuse and 12 volt battery positive to pin 4 of the trailer plug.
Ground the trailer back to the negative of the battery.
Plug your E12 flasher in again and see if the lights flash.
It really is that simple.

OK, Now I have to get a flasher and try this. :B
I can see where it might come in handy in some situations.
"... it doesn't have a battery, it's setup for boondocking..."
This line really confuses me :h
It's a 24' enclosed trailer converted to a Travel Trailer.

I think you missed the post where he said it was a cargo trailer converted to a travel trailer with no battery.

Pin 1 is negative is it not?

SoundGuy - I'm going to try this. Would this work? Just cut if off enough to fit inside the box chosen?

Sorry, I don't really have anything to sell nor am I in the business of manufacturing these things ... anyone that knows their way around a soldering iron can throw one together in no time, especially now that you have pics and a wiring diagram as a guide. 🙂

2112,how will I get power to it?
