Blue LEDs were not in commercial products in the 1980s, even if the technology existed. Perhaps due to cost, I don’t really know, but I was there and remember it well. In the 90s, companies went nuts with blue LEDs using them as power indicators in everything.
- Maursault 5y agoYou are simply mistaken. Volkswagen used blue LED in their 1989 model year dash, models presumably available in 1988. [1] [1] https://www.youtube.com/watch?v=snld2cT83qg&t=1m56s https://www.youtube.com/watch?v=snld2cT83qg&t=1m56s
- kube-system 5y agoI think you might be mistaken. Those are lenses that are shaped like LEDs but there are bulbs behind them. https://www.youtube.com/watch?v=Oqpyc8huRLE&t=20s https://www.youtube.com/watch?v=Oqpyc8huRLE&t=20s

- kingcharles 5y agoWe've reached peak YouTube. But that does answer the poster's claim. The lens is perfectly shaped to emulate an LED.
- madengr 5y agoI remember buying one in high school (1989 or 1990) for $15 from Digikey. It was in a clear package and put off barely any light, but it was a BLUE LED!
