think you're right Leo
I have a universal motorcycle zero draw flasher on order from superbrites that I expect to take care of the flashing issue (fingers crossed .... the "electronic LED flasher" I bought at the local big box auto store did not work). I have the headlight apart and access to all the internal connections which is how I was able to disconnect the instrument panel lights to verify side to side feedback through the tun signal indicator bulb as I suspected from tracing through the wiring diagram.
I'm puzzled as to why the standard turn signal bulbs on the opposite side don't also light up whenever the turn signal switch is activated, considering the factory wiring has the indicator bulb grounding through those bulbs. It must be the voltage drop and current draw of the indicator bulb doesn't leave enough voltage/current to light the opposite side lights.
