I just bought a 2 pole electronic flasher and made up a pigtail to plug it in, standard female spade connector fits the flasher terminals and small male spade connectors plug into the original plug the flasher was plugged into. Whole ball of wax was about 10 bucks. Works great, I have leds on the bike and trailer I pull.
Ok cool!! I was thinking there was an actual auto part that would fit, but if all I have to do is make my own pigtail...I can do that!

Thanks for all the info!
