Nitrous Express Flo-Thru Nitrous Pressure Gauges 15509

Bought it to give me an accurate pressure reading. By the color coded pressure readings I can read the gauge in low light settings since I do most of my racing at night. That way I can line back up to race and not have to pull over and get a flashlight to look at the pressure reading to make sure I'm still in range. Awesome product. I would like to see a fluorescent tip on needle that would help in low light settings to see if I'm in range.
