How do you wire a house for lights?

From that point on, electrically illuminated Christmas trees, but only indoors, grew with mounting enthusiasm in the United States and elsewhere. San Diego in 1904 and New York City in 1912 were the first recorded instances of the use of Christmas lights outside. McAdenville North Carolina claims to have been the first in 1956. The library of congress credits the town for inventing "the tradition of decorating evergreen trees with Christmas lights dates back to 1956 when the McAdenville Men's Club conceived of the idea of decorating a few trees around the McAdenville Community Center." However, the Rockefeller Center Christmas Tree has had "lights" since 1931, but did not have real electric lights until 1956. Furthermore, Phildelphia's Christmas Light Show and Disney's Christmas Tree also began in 1956. Though General Electric sponsored community lighting competitions during the 1920s, it would take until the mid 1950s for the use of such lights to be adopted by average households.
