I don't think GP's comment was about the use of incadescent bulbs, I think it was about soldering them onto the board.

- jacquesm 5y agoIn vibration sensitive applications that makes perfect sense.
- moron4hire 5y agoI mean, yeah, I wasn't in the room when the Space Shuttle was built. I don't know the "surprising level of detail" involved. I guess it's a round-about way of saying, "I'd like to know what those details were to understand why having to desolder burnt-out bulbs is better than using a spring-loaded, locking fitting."
- jacquesm 5y agoWhile it is always possible that a whole army of experts would miss something so obvious as the existence of spring loaded locking fittings (aka banjonet bulbs), the safe assumption is that they thought of it and rejected it for valid reasons. Vibration is a very nasty problem.

- jazzyjackson 5y agoi dont know that burnt out bulbs are a problem: you can trade reliability for efficiency: don’t burn the bulb at its brightest and it’s unlikely it will burn out
- dev_tty01 5y agoThe shuttle experiences severe vibration during launch. You don't want your indicator lights shaking loose during launch, so therefore they should be soldered.
