It didn't even dawn on me! I'm looking forward to seeing what you do with yours. I've been toying with the idea of plating the housings now that I have the illumination sort of figured out. They'd look good in brass or nickle 🙂 I'm just dreaming up stuff to do for sh*t* and giggles while I wait for output transformersDid you by any chance try the filaments along the bottom of the gauge?
