ONE Bare LAMP (NOT ALL SHOWN nor PC board) Extremely hard to find neon bulb with 3 posts/3 leads. I could not find any source anywhere else, so if you need one this may be your score! Can be used for "either/or" wiring to light the bulb from either or both of 2 sources. Originally from a vintage intercom system that indicators lit from one of two sources. Note you will need to add the normal current limiting resistors for use on 120V similar to what is used on the 2 pole type. They light up bright orange. Leads are short approx 1/4"to 1/2" but you can connect or solder on to that. Glass bulb, not counting leads, is about 3/4" from base to tip. Only a bulb is included not the PC board/resistors UNLESS you want to make an offer on all and the whole strip along with the PC board and resistors, however we do not know much about the rating or configuration-. there is 120k, 47k, and 33k by each lamp.
