At the time this photo was taken, Bluffton, Indiana was still using the old 6.6A series street lighting loop, which only a few cities and towns were using at the time. The street lighting circuits were changed over to modern parallel circuit system a few years after the photo was taken.

In this shot is a series lighting circuit regulator pole with the constant current regulator and other gadgets.
