The latest generation of production switchers and broadcast cameras provide two Tally states to ensure the talent knows how shots are being staged. The new cameras have standby and on-air indicators but the old prompters have just a single red light. The tally lights aren't bright enough to see easily and there's no adjustment. The suction cups that stick the tally light sensors onto the cameras fall off just to aggravate you. The talent can't squint enough to read the handmade labels used for camera IDs.
