The original GlowShift tachometer with a black dial and tinted glass is the perfect addition to high-performance vehicles. Designed to display engine revolutions from 0 to 10,000 RPM, working with single-coil gasoline engines. Seven solid color modes and two color cycle modes allow you to add a personal style to the interior by changing the display lighting with a simple press of a button located on the front panel. Equipped with stepper motor technology, which provides a combination of accurate readings and smooth needle movement. The illuminated red needle rotates 270°, and the color memory function remembers the last settings. Connecting the dimmer wire to the headlight switch reduces the gauge brightness by 30%, helping to minimize glare when viewing readings at night. Suitable for installation on the dashboard, A-pillar, or another spot inside the vehicle.
