Incandescent light bulb street in the world to be lit by an incandescent lightbulb was Mosley Street, Newcastle upon Tyne, United Kingdom. It was lit by Joseph Swan's incandescent lamp on 3 February 1879. Thomas Edison began serious research into developing a practical incandescent lamp in 1878. Edison filed his first patent application for "Improvement In Electric Lights" on 14 October 1878.

Philip Diehl (inventor) patents issued to Philip Diehl: Diehl erected the city's first arc light in front of the Corey Building in Elizabeth, which still stands at 109 Broad Street. Diehl's invention of the induction lamp was used by George Westinghouse to force royalty concessions from Thomas Edison. The Westinghouse Company bought Diehl's patent rights for $25,000. Although Diehl's lamp could not be made and sold at a price to compete with the Edison lamp, the Westinghouse Company used the Diehl bulb to force the holders of the Edison patent to charge a more reasonable rate for the use of the Edison patent
