Tinted 7 Color Water Temperature Gauge by GlowShift | Includes 1/8-27 NPT Electronic Sensor & Wiring, Multi-Color Analog Display, Black Dial, Smoked Lens, For Car & Truck

Despite what you read on forums, I have four of these gauges that have been in my semi truck for six years and they work perfectly, they are very accurate( I used my Computer & trucks sensors to measure accuracy) they look great and have everything you need to install.

This gauge looks nice, matches my glowshift boost gauge nicely. My only gripe is that when you initially turn it on, there's a weird noise from the motor as it does 1 sweep of the needle. After that it operates nice and quiet.

I just finished the installation and initial test of this gauge. The fit and finish is first-class and installation was a breeze (excluding the mandatory gymnastics that are required for working under any vehicle's dash). The gauge's face screens are razor sharp and the color choices coupled with the standard brightness levels yield a very readable display. This gauge offers the option of dimming the display when the headlights are on, but I don't plan to leverage the feature as the the light level is not offensive. This means it might even be too subdued for some users, as I always turn my dash illumination down very low as I find bright dash lighting to be distracting. I think the defining factor here is that only the necessary information is actually lit, as opposed to many vehicles where EVERYTHING glows, turning the gauge cluster into a fireworks display. The gauge is very readable and has the wonderful startup sweep, which I always find captivating (don't judge me!). The accuracy seems reasonable, but I have no baseline, so you'll have to trust me. But, rest assured that temperature measurement at the accuracy required in an automobile is NOT rocket science and even the Chinese can probably get the job done within reasonable tolerances. The variable here is whether or not the instrument endures. Initial impression? I very much like the product and will purchase more Glowshift bits as my truck project moves forward.

I needed a water temp gauge for my 1988 Nissan Sentra 4x4 wagon (bet you haven't seen one of those lately) since the dashboard gauge doesn't work. Paired it with the GlowShift 28mm hose adapter. Easy to install.

Since this is one of those things very easily construed as “operator error” or failure to install correctly, I had mine working for awhile. Something happened, maybe it got cooked, maybe I went over a speed bump too fast and it shut off completely. Screwed around with the wiring going over everything again and couldn’t find the issue. Contacted glow shift and they had me send it it for review, they sent it back and it worked again. Idk here’s better options. But if you want to be cool 1990s street racer you need to have all the RGBs.
