How Can I Get Trailer Lights to Flash when Disconnected from Truck

Question:

I am putting my 20foot enclosed trailer in a booth at a trade show. I want the lights to flash like hazard lights during the show as it sits there to attract attention. How or what do I need to make this happen? Would it be difficult? Here is a pic of my trailer.

If your trailer happens to have LED lights on it then what you could do is use a separate car battery and a couple of Custer strobe drivers, # STR-MRLY or # STR-QRLY, and connect the output wires to the trailer connector wires as needed. This driver is only rated for 420 milliamps though so only about 2 LED lights be driver would work. And if the trailer has regular incandescent lights then it will not work because the power draw would be too high.

Another simple option, battery powered emergency lights such as # HF20RL. You can place a couple of these somewhere and not have to worry about supplying power to the trailer wiring, separate batteries or special relays.
