GlowShift Tinted 7 Color 3 3/4 In Dash Speedometer Gauge by GlowShift

Easy to install and looks great in my Hummer H1. Really like being able to change colors on the gauge. Directions were easy to follow, I opted for the additional GPS module, much easier to calibrate.

Works amazing accurate speed and looks great . Easy to install

I ordered this for my daughters K5 because the big tires were throwing the factory Speedo off and updating the gauge to a GPS one is more accurate. Unfortunately I feel the description is misleading. When I purchased this it said “GPS Speedometer”. It is only GPS capable if you order the extra $60 GPS sensor. So after installing in the dash I went to wire it and realized I needed to spend more money and wait for another part. The other issues I have are it’s not bright enough. I have it wired correctly and it’s on the daytime setting. When I have it on a bright color the numbers are more visible but the needle is a very transparent red and not well lit, and you can barely see it. My last gripe is correcting the GPS speed was a pain. I don’t understand how it just can’t read GPS speed. You have a screw on the back that adjusts it up and down. So for me it read completely wrong out of the box. I spent 30min adjusting it using an Speedo app on my phone for accuracy. What’s weird is the GPS speedo on my phone doesn’t need adjusting, but this gauge does.

Love these gauges. Very vibrant colors. Really like how shallow they are,and the ease of installation. Wiring is simple as well. Instructions are well laid out. AWESOME AT NIGHT AND EASY TO READ DURING THE DAY.

The biggest thing that I don't like about the GlowShift gauges especially this one is the harness doesn't work, I need to print a 3D harness so the gauges can attach to the dashboard.
