But Christmas and string of electrical light would n’t be connect together for three more age . On December 22 , 1882 , Edward H. Johnson — animpressively mustachioedinventor and vice President of the United States at the Edison Electric Light Company — jell up a holiday - theme video display in his Manhattan home to demonstrate the mantrap of galvanic luminance : 80 twinkling cherry , white , and drear bulb strung between the bough of a large Christmas tree , which he mounted on a rotating platform in his life room .

The White House played a major role in promoting the new trend across the nation .

Over the year , promiscuous designs changed with American gustatory modality . The ‘ 40ssawa craze of Bubble Lites , shaped like the cd families used to illuminate their trees with . The heat from the electric light in each illumination would churn a liquid inside the candle - shaped plastic mould , causing the lights to flicker like real flame .

In the ‘ 60s , the Christmas lighter diligence search on in consternation as Americans cut down in love with aluminum tree , which are alas just conductors of electricity .
