As air bags are activated by accelerometers, and having an air bag inflate while you are driving could cause a crash, I think your analogy is appropriate in a way that might not be immediately obvious. In an emergency, too many warnings can be harmful. This can be a problem in hospitals, where every device beeps for all sorts of reasons. At Three Mile Island, the control panel became a 'christmas tree' of colored lights, when there was really only one problem: a stuck valve. It is especially a problem when the significance of the alarm is not clear, as when a sensor is a control input to multiple systems with complex algorithms. I would guess a warning light would be most useful in pre-flight checks, as a go/no-go indicator. It could also be an item in troubleshooting checklists (if the stick is shaking, yet the airspeed is good, is the AofA light on?)
