Oil lamp

Outside China, oil was not used as a source of lighting until the mid-19th century, when a colorless liquid was extracted from crude oil – a liquid which, when lit, burned with a flame strong enough to provide light without producing offensive smells. This liquid, used in lamps, was known as burning oil. (Inventions and Discoveries)
