Up for sale here is this used vintage Dialco indicator lamp. It has a faceted red glass or plastic lens. This is a nice extra-large-sized indicator lamp. This is an AC pilot light, though you may be able to put a DC bulb in here--I do not know. No bulb is included, sorry. This is a really cool vintage pilot light/indicator lamp, and it would look great on a home-made custom tube amplifier or what-have-you. Please see my pictures for details and ...measurements. US shipping and handling is $4, and international is $14. I accept Paypal. If you have any questions, please ask.
I have more pilot lights and other vintage electronics listed--feel free to take a look!
