The deficient digits did heal with use, especially the ten hour digit so I have no more excuse to sleep in after 1000. 🤣

It's common to surround nixies with a complementary colour of light such as blue, Due to the socket and tube base, it's not possible to do this through the bottom. So I tried placing a couple of LEDs in the background. Unfortunately the back of the nixie is opaque to prevent the glow from lighting the back or sides so the photo is the best I could do. 🤷
