Greddi Sirius 7 Colors LCD Head Up Display Gauge | Multi-Function Car Monitor

The Greddi Sirius 7 Colors LCD Head Up Display gives you a clear view of your engine's vital signs without taking your eyes off the road. It displays up to 10 different functions like boost, water and oil temperature, oil pressure, RPM, fuel pressure, and air-fuel ratio all in one compact gauge. With customizable 7-color backlighting, you can match the display to your dashboard or mood.

This universal gauge is designed for 12V vehicles and uses a flat glass, high-definition scale, and a long, narrow pointer for accurate readings and high visibility. The opening and ending modes can be selected from two variations, and you can set arbitrary warning values with a buzzer that has three loudness levels. Peak values and warning data can be stored, reviewed, and cleared, giving you full control over your engine monitoring.

Built with a durable ABS and LED construction, this gauge is made to last. The 7-color backlight lets you switch between colors to suit your style or to help differentiate readings at a glance. Whether you are tuning for performance or just want to keep a close eye on engine health, this gauge delivers reliable data in a clean, easy-to-read format.

Installation is straightforward for DIY enthusiasts, but please allow the engine and exhaust system to cool down before starting. This gauge is designed for 12V vehicles only, and do not disassemble or modify the unit as it will void the warranty and may cause damage.

Usage Scenario

Mark just finished installing a new turbo kit on his sedan. Before taking it to the track, he wanted to make sure his engine was running at safe temperatures and pressures. He mounted the Greddi Sirius gauge in front of his seat and set the warning buzzer to alert him if oil pressure dropped too low. On his first test run, the gauge showed his water temp climbing higher than expected. The warning buzzer went off, and Mark pulled over to let the engine cool. Without the gauge, he might have pushed the engine too hard and caused serious damage. Now he drives with confidence knowing he has real-time data at a glance.

Micro Comparison

Unlike basic single-function gauges that only show one parameter, the Greddi Sirius packs 10 readings into one compact display. Many multi-gauges require separate sensors and complex wiring, but this unit keeps things simple with a single housing and universal fit for 12V vehicles. The 7-color backlight also gives you a level of customization that most standard gauges lack, letting you match your dashboard lighting or create a unique look.
