Selling a set of two "Prime Instruments" model RG-193 dual-needle air gauges. I.e., can read two different pressures in one gauge, set of two is good for front/rear airbags, lockers, air tanks, or whatever. Support pressures up to 150 psi. Also includes four switches, and assorted fittings. You'll need to add the necessary hose lengths to complete an installation. Photos tell the story; sorry, I don't know much about them. I believe the gauges are illuminated, but have not tested them for this. I bought them to use on my Sportsmobile from a forum member a few years back and never installed them. Selling for what I paid for them: $25 + shipping. I'm guessing shipping will be around $10 or less. Local pickup in the Philadelphia, Pa., area is welcomed.
