7-Color Backlight Display Gauge Set | Boost Water Temp Oil Pressure Tachometer

Monitor your engine's vital signs with a single, versatile gauge. This 2.5-inch / 62mm racing meter packs up to nine different functions into one compact unit, from boost pressure to tachometer. The 7-color LED backlight lets you match your dashboard style, while the stepper motor delivers accurate readings for tuned and performance cars.

This gauge is built for 12V gasoline racing cars and works with 4, 6, or 8-cylinder engines. It includes the sensor and mounting bracket, so you can install it in a standard gauge pod. The 270-degree visible angle makes it easy to read at a glance, whether you are on the track or tuning in the garage.

Each gauge function has a specific measurement range. The water temperature gauge reads from 20 to 120°C, oil temperature from 50 to 150°C, and oil pressure from 0 to 1000 kPa. The voltmeter covers 8 to 18V, the turbo gauge reads from -1 to 2 x 100 kPa, and the tachometer goes up to 9000 RPM. You can also choose vacuum, air-fuel ratio, or ext temp functions depending on the model you select.

When you turn the ignition on, the gauge performs a self-check by flashing the display. The stepper motor provides faster and more precise needle movement compared to traditional air-core meters. This means you get reliable data that helps you keep your engine running safely under hard driving conditions.

Key Features and Benefits

- 7-color LED backlight that lets you switch the display color to match your interior or mood

• Stepper motor drive that gives faster, more accurate needle response for reliable readings

• Self-check start-up that flashes the display when ignition is turned on to verify function

• 2.5-inch / 62mm size that fits standard gauge pods and dash openings

• 270-degree visible angle that makes the gauge readable from multiple seating positions

• Compatible with 4, 6, and 8-cylinder gasoline engines for broad vehicle fitment

Who Is This For

- Racing and performance car owners who need to monitor multiple engine parameters

• DIY tuners and garage builders installing aftermarket gauge setups in 12V gasoline vehicles

• Drivers who want a customizable dashboard look with switchable backlight colors

• Anyone replacing a single failed gauge with a multi-function unit that includes sensor and bracket

Usage Scenario

Marco had just finished rebuilding the engine on his track-day hatchback. He needed a way to keep an eye on water temperature and oil pressure during hot laps. He installed this 7-color gauge in a single pod on the A-pillar. During his first session, the water temp reading climbed faster than expected, so he backed off and avoided a potential overheat. The stepper motor gave him smooth, instant needle movement that felt precise, and he set the backlight to red to match his other gauges.

Micro Comparison

Unlike single-function gauges that require a separate pod for each reading, this unit combines multiple measurements in one housing. The 7-color backlight gives you visual customization that most basic white or amber gauges do not offer. The stepper motor also provides smoother and faster needle response than older air-core designs, so you get real-time feedback without lag.
