Low Pressure Warning Lit

The MOROSO Low Pressure Warning Light (MOR49500) is a critical engine monitoring component designed for enthusiasts and mechanics who demand real-time oil pressure diagnostics. This adjustable warning light kit addresses a fundamental need in performance builds and older vehicle restorations: reliable, visible notification when oil pressure drops below safe operating thresholds. Whether you're tuning a high-output engine, retrofitting a classic car with modern instrumentation, or diagnosing pressure anomalies during a rebuild, this sender-and-light assembly provides the early warning system your engine protection strategy requires.

This kit delivers a complete solution: a pressure-sensitive sender, illuminated warning light, T-fitting for block integration, and pre-assembled wiring harness. The sender activates at 15–24 psi (user-adjustable within this range), catching pressure loss before bearing starvation or catastrophic failure occurs. The 1/8-inch NPT male thread is the industry standard for engine block oil galleries and aftermarket adapters, ensuring seamless installation on most V8, small-block, and modified engine platforms. Red indicator illumination provides unmistakable visual feedback in daylight or low-light conditions, and the compact footprint (4.05 × 2.95 × 5.1 inches) allows dash or panel mounting without bulk. Weighing just 0.48 pounds, the complete assembly adds negligible mass while handling the electrical and mechanical demands of continuous monitoring.

Experienced engine builders, restoration shops, and serious track enthusiasts rely on MOROSO pressure monitoring kits to bridge the gap between stock gauge clusters and precision telemetry. The 15–24 psi adjustability makes this unit suitable for mild street engines (lower threshold) and high-RPM performance builds (higher threshold), eliminating nuisance warnings while preserving safety margins. Installation requires only basic hand tools and mechanical knowledge: locate a suitable oil gallery on your block or manifold, thread in the T-fitting, attach the sender, secure the light unit, and connect the harness. This kit integrates seamlessly into custom dash builds, race car electrical systems, and period-correct restorations where factory oil pressure instrumentation is absent or unreliable. For any builder prioritizing engine longevity and diagnostics clarity, the MOROSO Low Pressure Warning Light delivers proven reliability and cost-effective peace of mind.
