LED Round Gauges
Features

Many replacement opportunities

L3’s LED round gauges are designed to replace a wide variety of outdated electro-mechanical and LCD technology indicators, including hydraulic pressure, hydraulic temperature, hydraulic reservoir level, RPM, air speed, altimeter, turbine inlet temperature, fuel flow, fuel quantity, engine oil temperature, engine oil pressure, and vertical scale indicators. LED round gauges are simple to install, using existing connectors and wiring.

Versatile, compact, lightweight

L3 round gauges provide the essential form, fit and digital technologies required in today’s modern aircraft. The two-inch round dial incorporates a solid-state design to increase tolerance to shock, vibration and temperature. Because the unit requires no software or microprocessor, it eliminates a key area for obsolescence and certification.
