Get a warning light at low oil pressure, well before a toasted motor. Everything is fine in the race car and you are just putting in laps, hitting your marks, and being smart. Then an oil warning light comes on. An oil warning light is used to let you know when you have a loss of pressure in your oil system. The best thing about a warning light? They are usually not on. Think of the aircraft dark cockpit concept - everything is off unless there is an issue. Use the Longacre Oil Pressure Warning Light Kit to give you advanced notice of a oil system leak early.
