I was afraid someone was going ask! I thought I read about it here, but I can't seem to find the exact place. I know I did some searchs for motorcycle LED flasher and found some links/threads where they are having the same problems we have--that the replacement LEDs don't draw enough amps to make the flasher work. Some recommend using a resistor to draw enough power, but they get hot and that means wasted power (which I don't have). Then somewhere else someone used one regular light (LittleBigMan?) and the flasher worked. If I understand correctly, inside the flasher is a bimetal strip that heats up when current is applied. When it reaches a certain temp, it bends and breaks the circuit. Then it cools and bends back to complete the circuit. I saw some total electronic flashers that work with just LEDs, but they start at $20 and go up from there. The flasher I have cost $8.
