Well after 45 years my lamps are burned out on the fresh air control unit.

PET says the bulb is a 900.631.129.90 but Google returns no results. I looked at some 911 places and maybe 900.631.132.90 is the replacement.

Does anyone know if there is an LED for this lamp? What is the base called (like BA9 for gauge lamps)?

I don't want to do this again in 45 years...

I believe that the small lights in the gauges are BA7S-Ws ...have you looked at these?

Not yet - but I will now - thanks!

I just looked at BA7 lamps and they have a base - the ones I need just have bare wire bent over each side. It is like this bulb #555 used in pinball machines except much smaller.

this is what you are looking for

Bulb 12v 1.2w

Thanks! I found it on the Bird Board for $1 each. I still would like an LED equal but these will work fine - cheers!

I have the same need. Is it possible to post the source other than AA?

Great...thanks!

Bumping this thread to see if anyone knows of an LED replacement... or just the stinking bulb base/size so I can look for myself.

EDIT: I think I answered my own question. Looks like they are 2721 bulbs. If so, dirt common and several led options available. I'll pick a couple up at the FLAPS tomorrow and confirm.

Pretty sure I have the LEDs in stock.
I will check in the morning and let you know.
