A couple of years ago I came across some vintage light bulbs while perusing the aisles of Home Depot. Since then, I’ve been looking for a project to use them in. I thought that it would be cool to use one as an indicator light and started to form this picture in my head of what it would look like. I wasn’t sure what the bulb would be indicating, but the idea was now in my head and once I figured out what to use it for, I’d have to make it.

All that to say that this project was motivated by the need to make an indicator light using one of those vintage bulbs.
