Princess Dial Light

[poplar1]

The dial light in a Princess phone is powered by 6 to 8 Volts AC. This is provided by a separate transformer, not the phone line. The transformer should be connected as follows:

Princess Model:                       Mounting Cord Conductors (Line Cord):
701B                                      Yellow and Black
702B and 2702B                      White and Black
702BM and 2702BM                 Yellow and Black

David:

Do you have data on the bulbs?  I seem to remember that the screw-based bulb takes a standard GE replacement bulb.  Were all incandescent bulbs for Princesses a standard off-the-shelf bulb?

I think both the screw-in type and the bayonet type are off-the-shelf. One is a GE46 but I would have to look for more info.

The newer style is a GE259. Here is an equivalent--6.3 Volts, 250 milliamps.
