The blue LED was supposed to be impossible—until a young engineer proposed a moonshot idea.

The first blue LED I ever saw was on the dashboard of my mom's VW Golf. I always wanted one like that, but now they're everywhere!

Agreed, though the original wasn't as bright as the one in the pic. It was a frosted LED and was relatively dim.

I like my car dashboard like I like my 1952 F-86 Saber night variant gauges... Orange

Before there were blue LED, the indicator light for full beam was a blue tinted incandescent bulb. My parents had a Volkswagen Passat from the 1980s (?) where the usually blue indicator light for full beam was a green LED, since blue ones were not invented back then.

Very interesting. I think my mom bought her car in 1996
