V Visitor Well-Known Member Aug 8, 2020 #2 If it is neon, the resistance across it will be very high when it's not operating. If the resistance is low, less than a few ohms, it's probably incandescent. If the resistance is very high or open circuit, it's likely neon.

(or you 'could' have instantly blown it?). But assuming they are nixie?, and not neon, then you might not have enough voltage to strike them.
