Gas lighting

Gas lighting is the process of burning piped natural gas or coal gas for illumination. Before the economicalization of electricity for general public use, it was the most popular means of lighting in cities and suburbs. Early gas lights had to be lit manually but soon gas lights could light themselves.

Other Usages

Gaslight is also the name of several movies. The verb, "to gaslight", or "gaslighting", following the premise of the movie, has come down to us as any attempt by one or more people to subtly convince someone else that they are losing their grasp on reality, through physical trickery or mind games, in order to gain some advantage over them.
