Another possibility is that it is in-line with a 12-volt device that needed a cheap voltage-dropping device, and the bulb serves that purpose. (Of course that would only work for a low-wattage device.) Did you check to see if it's powered? and does the bulb actually work?

Ignoring this device is a very serious matter. We may have to turn you in to the Feds, if you are operating with an inoperable device, even if it IS an undocumented and unknown one. :lol:

George, you must've been hitting the St Pauli Girl pretty hard today? No way you'd get a 24-volt device to work on 12 volts by putting a light bulb in series with it. IOW, you can't drop 12 volts to 24. :roll: That's NOT rocket science! :wink:

Speaking of the Feds, you could lose your A&P with a statement like that!

It was a typographical error that I failed to proof-read. I meant to say a SIX-volt device...which, in series with a 6-volt lamp (the "thing")... to enable it to operate in a 12-volt system.
