The light bulb was invented by Thomas Edison in 1879. Edison has the most patents in history with more than 1000. Prior to the light bulb, kerosene and gasoline lamps along with candles were the main source of light in homes. Although Ben Franklin discovered electricity Edison was able to harness this energy. Using lower current electricity, a small carbonized filament, and an improved vacuum inside the globe, he was able to produce a reliable, long-lasting source of light. The idea of electric lighting was not new, and a number of people had worked on, and even developed forms of electric lighting. But up to that time, nothing had been developed that was remotely practical for home use.

Homes now having electric light impacted the United States greatly. Workers didn’t have to depend on day light, and could work longer. The light bulb helped communication i.e. Morse code which needed light to signal a message. Harnessing electricity created a safer living environment. The dangers of candle fires were eliminated and people were able to see better during the night.
