GlowShift 2-1/16" Tinted 7-Color 18V Voltmeter Gauge Kit — 8–18V Analog Needle, Dimmer Wire, Matte Trim

GlowShift Tinted 7 Color 18V Volt Voltmeter Gauge Kit is a compact 2-1/16" (52mm) instrument that displays 8–18 volt battery readings with selectable lighting to match or customize your dashboard.

Compact, accurate, and visually adjustable, this GlowShift voltmeter gives drivers a clear readout of vehicle electrical health while offering seven solid colors and two cycle modes to blend with factory illumination or create a custom look. The tinted lens, matte black trim ring, and aluminum housing produce a low-profile, durable gauge that fits most dash openings and helps you spot charging or battery problems earlier.

How does this voltmeter help me monitor my vehicle's electrical system?

The gauge continuously reports system voltage from 8 to 18 volts so you can notice drops or spikes that indicate alternator, battery, or wiring issues. The illuminated needle and clear scale make readings easy to scan while driving without distracting glare.

• Voltage range: 8–18 V for cars and trucks
• Analog needle with precise scale for quick checks
• Helps identify undercharging or overcharging trends
• Tinted lens reduces reflection for daytime visibility

What lighting and color options are available and why do they matter?

Choose from seven solid colors—blue, red, green, teal, purple, white, and yellow—or pick one of two cycle modes that rotate through colors automatically. A dimmer wire lets the gauge reduce brightness by about 30% when headlights are on, making it easy to match cabin lighting and avoid nighttime glare.

• Seven fixed colors for matching factory lights
• Two color-cycle modes for a dynamic look
• Dimmer wire connection lowers brightness with headlights
• Tinted lens and matte trim for subtle, integrated appearance

How is the GlowShift kit installed and what hardware is included?

The kit arrives with everything needed for a straightforward install into a 2-1/16" (52mm) opening: a two-foot power harness, mounting bracket and hardware, a gauge visor, and step-by-step instructions. The plug-and-wire harness simplifies connections, while the bracket stabilizes the gauge in the dash or custom pod.

• Includes 2' power harness for standard wiring runs
• Mounting bracket and hardware for secure installation
• Gauge visor reduces glare and adds a factory look
• Clear instructions to assist DIY install or pro fitment

What build features and warranty support come with the gauge?

GlowShift backs the product with a one-year limited warranty, lifetime technical support, and a 30-day return policy for buyer confidence.
