So looking for a non powered visual indicator..ie...something that changes = color, that would be tripped by the micro that a tech would be able to look= at and say...failed board due to....X So when the board is running this "thing" can be controlled and then its fo= rever changed in state, even with the power off. Can't have smoke...so making a resistor crispy isnt allowed.
