One family I've recently noticed is the TT Chocolates and the Extra Light looks pretty close to what you need, but note the '1' in the image below is replaced with an uppercase 'i' (as suggested by Chris H in the comments below).
You can try some version Bernhard Gothic. This is Extra Light:
It's not free and clearly it has different curves than the tube photo. I guess in your application idea the whole presentation with glows and tube frames will be more important than exact curve forms. It should be enough that the glyphs are plausible, technically possible to be and work in a ...
Possibly worth looking at https://www.myfonts.com/fonts/kinobrand/nixin?tab=glyphs which appears to have been designed as a 'nixie alike' font. Though it puts a foot on the '1' in ultralight(but not on other font weights) and has a closed '4'. And of course it is not free.
Of course it depends where your nixie tubes were made... if they are genuine Nixie or ...
The full name for the family is "HBO Street Sans" (Carvalho Bernau, 2016). It was not put to use publicly until late 2018.
It is not freely available, and is a custom font family commissioned by HBO Digital Products.
It replaces Gotham, which was used up until that point.
Street 2, by the way, is the default or "middle grade" of this font....
If this is referring to Hanoded's license, I would say no you can't, sorry. A portfolio is created to show to potential clients, so it's for business. His list of examples is "postcards to your family, school purposes, and tattoos": that doesn't sound like "advertisements for my business" comes within that kind of thing. He means more like a poster for the ...
I don't know the exact font but I have a few ideas for your project (would really like to know what font it is though):
Period accurate geometric sans serifs for a jumping off point:
Univers - 1957 Futura - 1927
Also a condensed geometric font like Gotham Condensed (based on Futura but made in the 2000s) may give you the effect you want.
For the nixie ...

The most condensed is Quinze, but it may be too much. I found glyphs were touching each other in some cases. Then there is sudo, wich works great with line-height 1.0 and is an OK compromise if you really want to save space.
Many fonts are as condensed as Iosevka: M+, Terminus, Inconsolata Regular, etc......
An open typeface.
Inspired by Interstate (as Trebuchet might have been?). These derive from U.S. Highway signage, which is well documented geometrically, rather than as typeface/font.
Next to Nano you can also check out svg-buddy. That's a command line tool that automatically detects the used fonts in your SVG, downloads them from Google Fonts and embeds the base64-encoded fonts in the defs tag of the SVG. This ensures that the SVG is displayed the same way on all devices independent of the installed fonts on the user's system. Moreover, ...
