Review on GlowShift Tinted Color Transmission Temperature by Andrew Britton

great sensor. Installed as close to the exhaust pipe as possible in my 99 Runner with the T option. Easy installation with clear instructions. Not only tells you where your cables go, but why they should go there, making it easy to improve. It only took me about an hour to complete, and that's with installing the included mount that fits in my dash. The sensor shines well in daylight, about as bright as my stereos, but not annoying at night, and 30 percent dimmer with my headlights is fine. It can be set to hold any color all the time (there's even a permanent hot wire so it remembers your settings when you turn it off), as well as a 3 second hold for any color with instant transition to the next and gradually scroll. In general, I am very satisfied with the pressure gauge. I also buy an oil knife.
