5in NV/S Shift Lite Tach

The 5in NV/S Shift Lite Tach is a compact, night-vision-compatible tachometer designed for serious automotive enthusiasts and mechanics who demand precision engine monitoring in low-light conditions or tactical vehicle builds. This 5-inch gauge serves dual purposes: real-time RPM readout during high-performance driving and shift-light functionality that alerts drivers to optimal shift points, eliminating guesswork during spirited acceleration or racing applications. Whether you're tuning a modified engine, coordinating shifts during competition, or integrating gauges into a custom dashboard setup, this instrument combines functional accuracy with practical visibility.

Engineered with night-vision compatibility, the 5in NV/S Shift Lite Tach uses subdued lighting that remains visible through NV optics without blooming or washout—critical for operators running modern thermal or image-intensifier systems. The shift-light function triggers at a programmable RPM threshold, providing visual feedback that conserves mental bandwidth during high-stress driving scenarios where audio cues alone may be insufficient. The gauge face and housing are sized at 7.3 x 6.3 x 8.3 inches, allowing integration into custom gauge clusters, race car dashboards, or auxiliary instrument panels without consuming excessive dash real estate. At 2.15 lbs, installation is straightforward, requiring standard electrical connections to engine tach output and 12V power.

This gauge benefits mechanics building street-legal performance vehicles, off-road enthusiasts upgrading instrumentation, and tactical/military vehicle operators who integrate multi-spectrum optics into their platforms. It pairs well with engine management systems, turbo builds, and manual transmissions where precise shift points maximize power delivery and component longevity. Installation requires basic automotive electrical knowledge—connection to the vehicle's ignition switch, ground, and tachometer signal wire. Compatibility extends across most gasoline engines with factory or aftermarket tach outputs, making it an adaptable choice for restoration projects, restomod builds, and performance modifications where OEM cluster upgrades are impractical or unavailable.
