Please help identify this mystery LED!

[holly114]

I was hoping someone out there could help identify this mystery LED?

It was used in a old fashioned diesel pump that belonged to my grandfather which I have been hoping to refurbish. I understand it is interchangeable with RCA/Apollo DR-2000/2010 numitron tube which leads me to believe it would also be 4.5v on a B9A base. There are no markings to help identify it. If any one could help identify it would mean an awful lot. I hope I have posted this is the right section, and thank you very much for taking the time out to read.

Fuel pumps had 7-segment incandescent mosaic displays for a while.

"Old fashioned" and LED don't belong in the same sentence, at least not from my perspective.

I do not believe that entire device can be found new. However, the individual LED's can be replaced, if that is the problem.

What is the problem with it? Is it just a single LED out or a string? If it is a string, then I suspect a resistor has opened up. Can you post a picture with it lit up, preferably showing an 8?

It does look like LEDS and 6 SMT resistors, although I would suspect 7 resistors for seven segments.
