Hey, Old telephone guys, Doing ‘Barefoot in the Park’ and we have an authentic beige, Princess phone that lights up. And the light actually works; I’ve tested it with 6 volts. (GE 259 lamp) The cord has the 4 pin plug on it. If converted to the modular connector, will it work with a Tele-Q? Will it light up? Will that harm it? Thanks.
