Oil Pressure Warning Lamp/Indicator: Description and Operation

    The oil pressure indicator lamp is switched to ground by the oil pressure switch. When the lamp is switched to ground, ignition voltage flows through
the lamp, allowing it to illuminate. This indicates that oil pressure has dropped below a specified limit.
