Today at an estate sale i picked up a set of Noma Heavenly twinkle star lites, they are miniture(c-6) based string of 18 with two candelarbra socketed balest lames, with the miniture base sockets twinkling at random and burining individually with a shunt device in each lamp. I am figuring form the type of socket and the lack of the World Wide logo that it must be mid 60's, its piggyback connection is a hard molded rubber with the cord molded into the plug witch i would believe to be mid 60's. My problem is that teh 6-8 volt twinkle lamps do not seem to be twinkling, i only have 4 out of the 18 that will twinkle and i left the lights on for a good portion of the day. does anyone else seem to have this type of trouble, and yes i am sure they are twinkling type lamps because they all are fitted with bi-metalic strips inside the lamps.over all they are an interesting string, but i will note that when i found them they were connected with a flasher plug so this may have been a problem with this type of lamp? still a fun buy at 1 dollar.
