It would be very useful if Crossing Relay Boxes with automatic activation (Shunts) could output a redstone signal directly or via a comparator when activated.

for example:
if i want to build an pedestrian crossing with a flashing „stop“ bulb in a 1 bulb frame i would need a redstone signal from the Relay box to activate a traffic light control box

It would also be very cool if there was an option in addition to 1 light and 3lights to turn of the gate lights.

for example:
here in germany where i live we dont have gate lights so if i want to build such a railroad crossing in TC i would have to use a version wich doesnt have gate lights.

yes please, I could really use this feature

The chief problem is that crossing relay boxes accept power, so making it also emit power would be weird, I think?

Gate lights can be disabled by simply setting a Light Start Offset to a higher number than the gate's length. For example, if you had a gate length of 5 blocks, set your Light Start Offset to 6 and the gate lights will disappear.

Let's move this to the suggestions channel in Discord so that ideas on how to make this work from others can be more easily shared. Closing.

Maybe make it so the front accepts Redstone and the back outputs it.
