Reply to comment by Rampage_Rick in TIL in 1962 a General Electric engineer named Nick Holonyak developed the first LED light bulb capable of emitting visible red light. The same bulb was used in the 1964 stop animation animated TV special Rudolph the Red-Nosed Reindeer for Rudolph’s bioluminescent nose. by undergroundgeek

Bit of a longer video, but this lady has one of the best collections of early LEDs and other light and display elements and makes some very interesting videos
