EDIT: SOLD
I have several of these light guide displays for sale. They use a light guide for every single digit. On the back of the device are several small bullet-shaped incandescent bulbs that can be swapped out for LEDs.

One just sold on eBay for $100. I can't guarantee that all of the bulbs are working so I am asking for $50/each.

Well now... those look like something I could have fun with! Definitely interested but 2 questions first:

How many are for sale? Enough to make, say, a clock?

What's included: do you include the "connector" you're clipping on at about 2:55 in the video? The big circuit board?

Look into it later when the dust is clearing off the crater.

Two answers for you :)

Connectors - no. The PCBs were lost in a move :-/

In absence of connectors, what is on the back of the display units? Are the bases of the bulbs exposed or are the bulbs fully enclosed with some sort of pins / mating connector sticking out the back? IOW, is the missing connector piece actually part of the bulb sockets or is it just a connector?

Here are two photos of the rear. The bulbs are just friction fit. I know several of the bulbs are burned out and unless there is a good source of replacements, an LED source is probably the best bet.

The missing connectors clicked on the back and had spring contacts for the back of the bulb. The entire chassis is the common connection.

Okay, those pictures answer the question well. It's as I suspected - the missing half of the connector is part of the bulbs' "socket". LEDs are sounding like a good idea.

I'll email you shortly.
