What time period did Lamplighters exist in?

Lamplighters existed in the 18th and 19th centuries, during the height of gas and oil lamp usage. They were responsible for lighting and extinguishing street lamps in cities and towns, ensuring that the streets were well-lit and safe for pedestrians. With the advent of electricity and electric streetlights, the need for lamplighters diminished and they eventually became obsolete in the early 20th century.
