This is my circuit board / coil cord belt attachment. Unfortunately I couldn't find nixies, so I settled for the next best thing... flash cube bulbs (blue dot Sylvania cubes to be exact). They run about $6 for a set of 3 cubes, each cube containing 4 bulbs. They are old though so not all camera shops will have them, and you'll probably have to ask for them. Hope you enjoy.
