below is the Jpeg's of an electronic wizz kids design for an indicator electronic " relay " it does work had one on my T & T RD400.
Since it does not require a specific load "it just works" as he put it.
I hope this will put you guys using all LED indicators and part LED indicators & tail converters et al out of your misery.
The point to watch is the resistor calculation for wattage if using bulbs is not more than 45 watts per bike side ie drawing not more than 4Amps (although the switching transistor can handle 7 amps but does generate alot of heat at that point and may require a heat sink.
YMMV, please do not ask me anything beyond what you see this i NOT my design but I do have it working :-}
