lot of 4 Dialco 1" Indicator Lamp pilot lamp Beehive Hot Rod light Dashboard

Description

Classic bee-hive pilot indicator lamps from the 1950's or 1960's.  stamping says 75W 125V.  1" diameter on shaft.
Colours are orange, green/blue, red and white. Colour is approximate and not guaranteed, since i held them up against the light to check the colour. I did not test these items, because they are outside my specialty; I am not sure if they take AC or DC power, and I don't want to damage them.
They were carefully saved by someone and purchased as part of an estate electrical lot, so I am quite sure they are working.  If it turns out any do not work, I will re-fund 25% of purchase price for each one that is not working.
all screws and plates are intact.
