I want to make a small clock using Nixie tubes (for the cool/retro/steampunk look of them), I have some basic knowledge of electronics, but I have never done anything with more than 12V DC and ~10A. I saw that Nixie tubes are usually using 3mA at 180V in order to make the Neon glow and I am concerned with the safety concerns.

Because I do not want to hurt myself with a shock of 180V caused by a mistake due to my poor experience with high voltage, I wonder if some indicator tubes that look like Nixie ones are functioning in low voltage/current ?

I know no Nixie tubes at low voltage can not exist because the gas needs to be excited to produce light, thus, the "look like" is very important.

    \$\begingroup\$ Use a HD LCD with a picture of a nixie tube display. Nobody will notice the difference! \$\endgroup\$ – Andy aka May 29 '17 at 13:33

    \$\begingroup\$ One trick I've seen is multiple layers of clear Acrylic with a digit engraved in each layer and each is separately edge illuminated with LEDs. While it doesn't really look like a Nixie, it has the same 3D look. Unfortunately, you'll probably need to find someone with a laser engraver to make the panels and make the LED assembly yourself. \$\endgroup\$ – DoxyLover May 29 '17 at 18:53

No, low voltage nixie tubes do not exist. But if you're after that nixie tube "look" you can buy Numitrons that work at 4.5v.

https://www.youtube.com/watch?v=uT5W2IU7Ft0 for an example of what a Numitron looks like.

To answer your question succinctly, no they do not exist.

Yes they do look for a tube number GE Y1938 , i own 4 , datasheet is on google

    \$\begingroup\$ That a vacuum fluorescent display (VFD), not a Nixie tube (neon gas discharge). Completely different technology. Also, it's 7-segment, not fully-formed digits like a Nixie has. \$\endgroup\$ – Dave Tweed Jun 12 at 23:07
