52MM 7-in-1 Car Gauge Set | LED Dual Display with Sensors for 12V Gasoline Vehicles

Monitor seven critical engine parameters at a glance with this 52mm gauge set. It features a 77-color LED dual display that combines analog and digital readouts for water temperature, oil temperature, oil pressure, boost, vacuum, voltage, and RPM. Designed for 12V gasoline cars, this set includes the necessary sensors for installation.

This gauge set gives you a complete view of your engine's health in one compact package. The 52mm diameter gauges fit standard pods and panels, making them a practical upgrade for monitoring performance. The high-speed stepper motor provides quick and accurate needle response, so you get real-time data as you drive.

The dual display design shows both an analog needle and a digital readout, giving you two ways to read the same information. You can switch the LED backlight color using the button on the gauge face, allowing you to match your dashboard lighting or personal style. The set is built for professional installation and comes with an installation manual to guide the process.

Each gauge is powered by your vehicle's 12V system and draws a maximum of 0.3A for ignition and illumination. The voltmeter reads from 8 to 18V, the boost gauge covers -30 to 30 PSI, and the vacuum gauge reads -30 to 0 In.Hg. Water and oil temperature gauges range from 40 to 140°C, while the oil pressure gauge goes from 0 to 100 PSI. The tachometer measures up to 10,000 RPM and is compatible with 4, 6, and 8-cylinder gasoline engines.

Key Features and Benefits

- Seven-in-one gauge set that monitors water temp, oil temp, oil pressure, boost, vacuum, voltage, and RPM, so you get complete engine data from a single installation.

• 77-color LED dual display with analog and digital readouts, giving you clear visibility and customizable dashboard lighting.

• High-speed stepper motor that delivers quick needle response, providing accurate real-time readings as you drive.

• Button-controlled LED color switching, allowing you to match the gauge lighting to your personal preference or interior style.

• Includes sensors for water temp, oil temp, oil pressure, boost, and vacuum, so you have everything needed for installation.

Who Is This For

- Car enthusiasts who want to monitor multiple engine parameters without installing separate gauges for each reading.

• Owners of 12V gasoline vehicles with 4, 6, or 8-cylinder engines looking to add performance monitoring to their dashboard.

• DIY mechanics and tuners who need accurate data on boost, vacuum, oil pressure, and temperatures during engine setup or troubleshooting.

• Drivers who prefer a customizable dashboard look with the ability to switch LED colors to match their vehicle's interior.

Usage Scenario

Mark had just finished rebuilding the engine in his project car. He needed a way to keep an eye on critical temperatures and pressures during the break-in period. After installing this 7-in-1 gauge set, he could watch the water temp climb and the oil pressure stabilize as the engine warmed up. The dual display let him see the analog needle sweep while the digital readout showed exact numbers. When he took the car for its first test drive, the boost gauge confirmed his turbo was spooling correctly, and the tachometer helped him shift at the right RPM. The whole setup fit neatly into his single-din slot, and he set the LED to blue to match his interior lights.

Micro Comparison

Unlike buying individual gauges that require separate wiring, pods, and sensor setups, this 7-in-1 set consolidates everything into one package. You get six different gauge functions plus a tachometer, all running from a single 12V power source. The dual analog and digital display gives you the best of both reading styles, while the 77-color LED backlight lets you personalize the look. This set is a space-saving and cost-effective solution for anyone who wants comprehensive engine monitoring without the clutter of multiple separate gauges.
