Reply to comment by markydsade 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

Yeah, LED seems absolutely wild to me when stained glass incandescent would have worked great. However PID dimming was possible at the time.

I’ll have to rewatch but I think in some scenes you can see the filament of the bulb.
