I'm trying to figure out how best to make a relay switch properly operate LED turn signals. I've read references to both using resistors on a normal flasher relay switch, as well as buying a flasher relay specifically for LED turn signals. I opted to order a (supposedly) LED specific flasher relay ( http://www.amazon.com/gp/product/B000CMF38A/ref=oss_product ) but I can't get it to work. I also have a regular, universal flasher relay; I've heard references to putting resistors in right before the standard flasher switch, but no one actually said what resistor specifications to use. Anyone out there know? Or, anyone know of an LED specific flasher relay switch that actually works? Or maybe how to make the one I do have (Grote 44891 Two Prong Led Flasher) work? Help on this problem would be GREATLY appreciated.
