Review on 🚗 GlowShift Tinted 7 Color Volt Voltmeter Gauge - 8-18 Volt Range - Black Dial - Smoked Lens - 2-1/16" 52mm: Accurate Voltage Monitoring for Your Vehicle by Greg Muin

I've been a glowshift user since I received my glowshift sensors in the mail and tested them for functionality. It's very worth it! I have this sensor along with a transmission temp sensor and a water temp sensor. All 3 are great. I like the action of the stepper motor when "booting" after turning on the ignition. Very easy to install. It is very bright during the day and especially at night. The only downside, but nothing to worry about, is that the included wiring harness is only a foot long. So expect to buy additional cables. I recommend 18 gauge (the instructions actually say 18 gauge, but I could already tell which gauge to use from the wiring). I purchased swivel gauges (TabStore DBPower® 2" 52mm Auto Universal Gauge Holder Cup Mount Cap 360 Degree Swivel 45 Degree Angle) from Revain and they work great with some hot glue to ensure a secure and tight fit ensure Fits.Highly recommend.Below are 3 photos of them installed in my 1994 Chevy C1500 with the sensors mentioned above.
