GlowShift’s White 7 Color Series 2 Inch Tachometer reads from 0 to 10,000 RPM and can be installed into any 1 through 10 cylinder gas powered engine, making it a great addition to any performance vehicle. This tachometer includes incredible features that include 7 color LED through dial lighting, stepper motor technology, an illuminated red needle that will sweeps 270 degrees, as well as a white gauge face with a magnified clear lens. The included stepper motor technology gives this tachometer the perfect combination of incredibly accurate readings combined with extremely smooth needle movement. GlowShift’s 7 Color through dial lighting lets you select from 7 different solid colors, along with 2 color cycle modes allowing you to match your factory dash lights or add a custom look to the interior of your vehicle. Connecting this gauge to your factory headlight switch allows it to dim up to 30% for easier night driving, and with the color memory recall feature you don’t need to worry about adjusting the color of your gauge every time you turn your vehicle. GlowShift’s 2 inch tachometer is installed by connecting the included color coded wire harness to the negative side of your coil, your tachometer test port, or with a tach adapter.
