What does a lamplighter do?
100 or so years ago streetlights (lamps) were powered by natural gas. The lamps were off during the day, of course, but had to be individually lit come nightfall. The person who went up and down the street lighting the gas lamps was the "lamp lighter." Not much call for this talent any more except maybe for Lamp Light Square in St Louis.
