When did lamplighters become obsolete?

Answer 1

Lamplighters began to become obsolete in the late 19th to early 20th century with the widespread adoption of electric street lighting. The introduction of electric lamps, which required less manual upkeep, significantly reduced the need for individuals to light and maintain gas lamps. By the 1920s, most cities had transitioned to electric lighting, leading to a decline in the lamplighter profession.
