Is this alert meant to be shown during the match? See Eric's post.

Do you want an alert light on at other times such as to remind yourself to disable the shooter when removing the robot from the field? I'm afraid you wouldn't be able to do that. All power must go through your control system that is disabled when the match ends.

It sounds like a noble safety goal, but that's not the way to accomplish it.
