Since gauges are not a block nor a sign. I think we need some stuff like this
Annunciator Panel which is a gauge block and has 3 states (on/amber/off) maybe more if it could be
Since nixie tubes logic is already present a flush wall mounted one will be beneficial too
And as a way to check or indicate output of some kind of complex logic mounted single color or multicolor (like dual or triple) pilot lights
Could enable user to create a proper dashboard (indicator wise)
but for actuall control room stuff we need 1/4 of the size button/lever/hold button (for logic which works after holding button for certain amount of time) and analog lever or preferably a small itty bitty horisontal dial which could work but clicking or holding RMB and scrolling mousewheel (it could also house custom amount of numbers or pictograms from unicode like arrows or symbols)
