Nice find.
LED lights don't play nice with most flashers. Seems like they could make a flasher that didn't care, but it would take an extra wire to ground. I had to add resistors to the signal lights on my Sur-ron to make the flasher work. Downside of all that is you can't really tell when one of the lights quits working. With the old-school flashers, the flashing rate would increase if you burned out a bulb. With LED lights, they don't burn out so often.
