These LEDs are designed to fit nicely into start buttons, launch ball button & coin door assemblies requiring 12v. They are slightly thinner than most other LED bulbs allowing for a perfect fit.
They are also great for use in uncontrolled (general illumination) & controlled (insert) applications that run on 12v; generally used in Spooky, American Pinball & Jersey Jack Pinball pinball machines.
Jersey Jack Pinball #24-0017-00 & 24-000017-00.
