I vote for Muddy0409's except, I would put a resistor in series with the processor output lead to limit the output current. This is exactly what I would have proposed except I would have used a couple of zeners instead of the extra led in each leg... If you have an extra inverter available you could modulate one side of a bidirectional led (red/green) and connect the other side thru a resistor to the processor output pin and then place it either high or low and finally to an input state to shut it off.....
