The street of lights   When we are talking about street lights, we have to start from Christmas lights decoration. Christmas lights (also known as fairy lights or string lights) are lights often used for decoration in celebration of Christmas, often on display throughout the Christmas season including Advent and Christmastide. The custom goes back to when Christmas trees were decorated with candles, which symbolized Christ being the light of the world The first known electrically illuminated Christmas tree was the creation of Edward H. Johnson, an associate of inventor Thomas Edison. While he was vice president of the Edison Electric Light Company, a predecessor of today's Con Edison electric utility, he had Christmas tree light bulbs especially made for him. He proudly displayed his Christmas tree, which was hand-wired with 80 red, white and blue electric incandescent light bulbs the size of walnuts, on December 22, 1882 at his home on Fifth Avenue in New York City. Local newspapers ignored the story, seeing it as a publicity stunt. However, it was published by a Detroit newspaper reporter, and Johnson has become widely regarded as the Father of Electric Christmas Tree Lights. By 1900, businesses started stringing up Christmas lights behind their windows. Christmas lights were too expensive for the average person; as such, electric Christmas lights did not become the majority replacement for candles until 1930. In 1895, US President Grover Cleveland sponsored the first electrically-lit Christmas tree in the White House. It was a huge specimen, featuring over a hundred multicolored lights. The first commercially-produced Christmas tree lamps were manufactured in strings of multiples of eight sockets by the General Electric Co. of Harrison, New Jersey. Each socket took a miniature two-candela carbon-filament lamp. From that point on, electrically-illuminated Christmas trees (only indoors) grew with mounting enthusiasm in the US and elsewhere. San Diego in 1904, Appleton, Wisconsin in 1909, 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, Philadelphia'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. Christmas lights found use in places other than Christmas trees. By 1919, city electrician John Malpiede began decorating the new Civic Center Park in Denver, Colorado, eventually expanding the display to the park's Greek Amphitheater and later to the adjacent new Denver City and County Building - City Hall upon its completion in 1932. Soon, strings of lights adorned mantles and doorways inside homes, and ran along the rafters, roof lines, and porch railings of homes and businesses. In recent times, many city skyscrapers are decorated with long mostly-vertical strings of a common theme, and are activated simultaneously in Grand Illumination ceremonies. In 1963, a boycott of Christmas lights was done in Greenville, North Carolina to protest the segregation that kept blacks from being employed by downtown businesses in Greenville, during the Christmas sales season. Known as the Black Christmas boycott or "Christmas Sacrifice", it was an effective way to protest the cultural and fiscal segregation in the town with 33% black population. Light decorations in the homes, on the Christmas trees, or outside the house were not shown, and only six houses in the black community broke the boycott that Christmas (wikipedia)
