GlowShift’s Tinted 7 Series 200 PSI Air Pressure Gauge is perfect for any vehicle with air brakes or an aftermarket air suspension system installed. This mechanical air pressure gauge reads from 0 to 200 PSI with the included 1/8-27 NPT male fitting that is located on the back of the gauge. GlowShift’s air pressure gauge boasts some incredible features that include, 7 color through dial lighting, a low profile magnified tinted lens, and an easy to read illuminated red needle that will sweep 270 degrees for maximum accuracy. GlowShift’s 7 Color through dial lighting lets you select from 7 different solid color, along with 2 color cycle modes, that allows you to match your factory dash lights or add a custom look to the interior of your vehicle. Connecting this gauge to your factory headlight switch allows it to dim up to 30% for easier night driving, and with the color memory recall feature you won’t have to reset the gauge to your desired color every time you turn your vehicle on.
