Clearly I was referring to commercial off-the-shelf products rated for aerospace use, not experimental lab prototypes. Regarding your father's car, I'd suggest the indicator in question is either an after-market addition, or an original incandescent mini-bulb behind a blue plastic filter. The latter was a common way to implement coloured dashboard lights back then.

I should have known because when most people talk about LED they mean "hardened for aerospace LED." Right? Come on. > Regarding your father's car Nope. Volkswagen used what anyone would recognize as an ordinary blue LED in their 1989 model year dash, along with ordinary red, green & yellow LEDs.

  In my 1984 (A1) Rabbit GTI the indicator that looks like a blue LED is a piece of blue plastic backlit with a white lamp. The A2 cars (including the 1989 Jetta) used the same setup.

  No. Those are blue lenses only. They did not use blue LEDS in 1989: https://www.youtube.com/watch?v=Oqpyc8huRLE&t=20s https://www.youtube.com/watch?v=Oqpyc8huRLE&t=20s
