Class 1 has introduced a new series of backlit pressure gauges, which use LEDs to light the liquid-filled gauges. The lighted gauges are available in red, green, blue, yellow and white for 2.5-, 3.5-, 4.5- and 6-inch gauges. They offer bright illumination to increase visibility under extreme fire incident conditions. Class 1’s rugged design allows for steady needle viewing under pulsation and vibration normally seen on fire apparatus
