Considering that they used a lot of vintage Airplane parts for mostly everything in the OT, the IG-88 head, Lightsaber parts, millennium falcon, and such things. It would not suprice me if those red blue and orange light are from airplanes as well.
That's an good advice. I think there are some airplane warning lights from airport antennas.
This are some new lamps the look very similar.
So I must look in the 1950 to 980 era of these lights.
I have tried to identify the red and blue lights. I think there are a emergency beacon or a taxiway light or something similar. I´ve searched for ribbed blue vintage lights. If anyone have old production photos from the cantina scene would be great.
The table lamp looks a lot like the one in my bathroom's ceiling. Ceramic base, thick milky glass. The base must be sunk into the table. I'm sure there are many like it.
