Not sure if this is of any interest, but you might consider if the led outputs can support additional loads. For example an application may want to drive logic for actual traffic control. I used a 3rd party traffic controller to drive a 4 way intersection using the MTH traffic lights. I added additional logic to control traffic. The vehicles start and stop on green and red. On yellow, it depends. If the vehicle is close to the light, the vehicle runs the light otherwise the vehicle stops. Actually, my vehicles are trolleys.
