Primarily Petroliana Shop Talk Forums Thread Like Summary - Blinker Flashing Marquee Arrow

Would anyone here know what correct style bulb should be used with these type of marquee displays? or where to purchase such period correct bulbs? thank you!

I purchased mine from Amazon, they also have led to look like originals
but more money, especially when you are doing both sides (90+)
Good luck and share a picture when it is all lit up!!
