When was gaslight invented?

Gaslight was invented in the early 19th century, with the first practical use of gas lighting occurring in 1807 when Sir Humphry Davy demonstrated it using coal gas. The widespread use of gas lighting began in the 1810s, particularly in cities like London and Paris, where it was used to illuminate streets and public spaces. By the mid-19th century, gaslight had become a common lighting source in homes and businesses.
