This new muscle gauge is 60mm diameter. With special dial surface printing technology, this gauge has a metallic tone dial plate with concave scales and fine circular hairlines that give a premium texture, and by using the high light-transmitting glass, this instrument has a stunning appearance and performance. At the same time, perfect programming and excellent quality can well meet your requirements, such as fast response, available buzzer, dimming, 9 colours options etc.


This gauge uses 8 pieces of high-quality LEDs as the backlight,  it brings a high brightness backlit in the daytime, and the brightness will be reduced to suit your eyes when you turn on the headlight in the nighttime. The gauge has the red Warning LED, it will blink and the buzzer will sound in the meantime when the oil pressure is lower than the setting value, and the blue PEAK LED will display the highest value for 3 seconds when you turn off the engine.

9 Color Options

This gauge can display White, Red, Purple, Sky Blue, Yellow, Blue, Gold, Teal, Green and Pink. You can adjust one solid colour or 10 colour cycle display. It's easy to adjust the colour of the gauge to match your factory dash lights or create a custom look inside of your car or truck. With the Color Memory feature, you won’t have to reset the colour of the gauge every time you turn on your vehicle.

Daytime/Nighttime light

There are two modes for the brightness and colour setting: Daytime mode and Nighttime mode. You can set the different colours and brightness in different two modes, then you can turn on/off the headlight to switch between Daytime and Nighttime modes after you connect the Yellow wire( in the power cable) to the headlight fuse.

What Are the Benefits of the Air/Fuel Ratio Gauge?

  • Analog gauges are exposed directly to the source of their measurements, which in this case is the voltage output of an oxygen sensor. Fluctuations affect the needle proportionately, and these variations translate into accurate readouts. As a result, this mechanical gauge will immediately demonstrate any changes in the air/fuel ratio with pinpoint precision. Given the smooth needle movement, any rate of change can be detected very easily.


  • One year limited warranty and free lifetime tech support. You will also have access to an unrivalled customer support experience in the event you have any questions about our gauges, pods and accessories.
