Hello, looking for advice on Wig Wags. We have a set (just the one Wig Wag signal) outside a fire station to be replaced. It has its own ancient controller. 80m along the road is a junction with another controller (put in a number of years after the Wig Wags), so there’s a hurry call when the button in the station is pressed which gives priority to westbound traffic if the fire trucks are heading westbound.

I guess my question is this – is there any need for me to replace the Wig Wag controller? Could a new Wig Wag signal be taken back to the junction controller and the controller config updated accordingly?
