Hydraulic Pressure... When gear actuator hydraulic seals, etc. get old, you'll see the red Unsafe light momentarily, and if you're looking at the ammeter, the amps jump up as the hydraulic motor runs, the pressure forces the gear up against the up-switch, thereby shutting off the pump; amp load drops, and then after a while, it happens again. Eventually maintenance gets around to fixing things when the time is ripe.
