Early Warning Devices

Your gauges register a problem, you grab a quick glance at the gauges, and recognize that a problem exists, but your engine may have already suffered expensive damage. Our warning switches and lights can help save costly repairs by alerting you of problems before damage has a chance to occur.

The very first Pegasus part number, #1003, came about because Pegasus founder Chris Heitman raced a Formula Ford with a bad habit of throwing oil pump belts. By the time a commercially-available 20psi oil pressure switch would trigger the warning light, the engine was already damaged. Chris designed a 30psi oil pressure switch to turn on the light sooner so he had a chance to save the engine.
