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.

Nice call rjenkins. It's a nixie tube. There's some discussion about them here, including a link to a Russian datasheet.
