How can I make my TT lights flash unhooked from my truck?

[DavidSanders]

I am attending a trade show for my employer and we will have our 24' enclosed trailer converted to a TT there on display. My VP wants me to find a way to make the trailer lights flash, exactly like it would look if you cut the hazard lights on. Only thing is, the truck we are pulling it there with wont fit in our display booth. So I am trying to come up with a wiring technique or method using a battery that would allow the trailer lights to flash on and off (to attract the attention of the patrons walking by) using the existing plug/wiring powered by a battery. I was thinking of using a jumper maybe, using diodes or even finding some way to incorporate a flasher kit like the one in the link below.

Any suggestions? Thanks in advance!

You need a battery on the trailer to haul it anywhere. How will your emergency breakaway system work without a battery? Connect the battery to the typical trailer connectors. The trailer's umbilical should have a post that is connected to the battery (this is for charging with the vehicle while driving). Connect a heavy duty flasher in the umbilical slots for that 12V power and the marker/tail lights.

Not all trailers have break-away brakes. In Ontario we are not required to have them so my 30 foot TT did not have the module when sold new. My 6x12 utility trailer is rated for under 3000 lbs so I don't even have brakes on that axle - new from factory.

Did you do it as I described in my PM?

I sent her your # but she works nights now and may not have time.
We'll see.

Read your PM's.

14 gauge would work, 12 gauge would be overkill, but for a price difference of maybe a buck I would probably go with the 12 gauge.

Use 10 awg or 12 awg. It will be overkill for the current involved but will deliver the full voltage from the battery to the lights.

12 gauge wire should be more than sufficient.

I had to Google "China Spring" to find out it's a small community northwest of Waco, Texas which is ~ 1500 miles from where I am, so no, I don't know anyone in China Spring nor Texas for that matter. Sorry.

Disregard, the guy that offered assistance in China Spring quoted your post.

Trailer Lights Dongle (3 pics)







In the situation described by the OP a G24 deep cycle battery would provide sufficient power to flash the lights on a typical travel trailer for days. I use my trailer lights dongle every time I back our trailer from the street and on to our driveway, and should I ever be forced to leave the trailer on the side of the road I have the ability to flash ALL the trailer lights for maximum visibility for as long as may be necessary.

Anyone at a U-haul that does hitch installs or any place that does hitch installs could probably make this for you. U-haul even has the heavy duty flashers for sale, I think.
