Prosport Electric Boost Gauge

his electrically-actuated boost gauge reads 30 in-Hg to 30 psi. Choose from green/white (switchable) or amber/white (switchable) backlighting, each with red illuminated needle. When off, the gauge is completely dark, like some of those other, more expensive gauges. You can wire the gauge to be the same backlighting color night and day, or switch from one color to the other when you switch on your lights at night.

Comes complete with vacuum hose, vacuum tee, gauge hood and mounting bracket (see inset pic for a view of what's in the box). 52mm or 60mm gauge size. And yes, since this gauge is electric and not mechanical, it DOES have the "opening ceremony" behavior when it powers on!
