I was thinking neon lights. I mean that’s basically an arc, just spread out. I think I heard that there’s a glow in vacuum too, just not as nice as with neon.

Well, a quick search turned up this: Vacuum Arc
However, like the above comment, it seems to refer to freeing electrons from the conducts, so, IMHO, you no longer have a vacuum.
If you could somehow maintain a perfect vacuum; I wonder how this concept Virtual particle would come into play (or if it would at all).
