This probably falls into the category of an urban legend (and also gives
away how old I am!)

The British Electricity Board, many years ago, was reputed to use a DC
pulse on the AC line to turn the street lights on and off (how about that
for a narrow-band communication channel).  Then TV manufacturers started to
build transformerless sets to save weight, with, I believe, voltage
doublers to boot.  Every time one of the sets was switched on or off, it
had a VERY interesting effect on the street lighting!
