Christmas lights
Det første kendte elektrisk oplyste juletræ blev skabt af Edward H. Johnson, der var en samarbejdspartner til opfinderen Thomas Edison. Mens han var vicepræsident for Edison Electric Light Company, en forgænger for det nuværende elforsyningsfirma Con Edison, fik han fremstillet pærer til juletræer specielt til ham. Den 22. december 1882 viste han stolt sit juletræ frem i sit hjem på Fifth Avenue i New York City, hvor han havde 80 røde, hvide og blå elektriske glødepærer på størrelse med valnødder, som var håndfortrådt. De lokale aviser ignorerede historien og betragtede den som et reklame-stunt. Den blev imidlertid offentliggjort af en journalist fra en avis i Detroit, og Johnson er blevet bredt anset som faderen til elektriske juletræslys. I 1900 begyndte forretninger at sætte julelys op bag deres vinduer. Julelys var for dyrt for den almindelige borger, og derfor blev elektrisk julelys først i 1930 den mest udbredte erstatning for stearinlys.

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.
