Hi folks, can anyone tell me what this component marked “V4” is and maybe if there is a way to test it?

No, V1, V2, V3, and V5 look like miniature bulbs

V4 looks like a gas arrestor or gas discharge tube. The others look like neon bulbs.

Thank you! You are exactly correct. Is there any way I can tell if it's good or not? I suspect it's probably good as I don't see any signs of leakage or physical damage.
