A pilot light is a small gas flame, usually natural gas or liquefied petroleum gas, which serves as an ignition source for a more powerful gas burner. Originally a pilot light was kept permanently alight, but this wastes gas. Now it is more common to light a burner electrically, but gas pilot lights are still used when a high energy ignition ...
Gas lighting in the historical center of Wrocław, Poland, is manually turned off and on daily.. Gas lighting is the production of artificial light from combustion of a fuel gas such as methane, propane, butane, acetylene, ethylene, hydrogen, carbon monoxide, coal gas (town gas) or natural gas.
As the building's heat source was natural gas, there was a heater with a pilot light in the basement. As the gas built up, the heater's pilot light became the ignition source of the explosion. A year later the company was fined US$300,000 by the New Jersey Board of Public Utilities after their investigation found multiple safety violations. No ...

Pilot-controlled lighting (PCL), also known as aircraft radio control of aerodrome lighting (ARCAL) or pilot-activated lighting (PAL), is a system that allows aircraft pilots to control the lighting of an airport or airfield's approach lights, runway edge lights, and taxiways via radio.
He and his workers changed fireplaces by inserting bricks into the hearth to make the side walls angled, and they added a choke to the chimney to create a circulation of air inside the chimney. In the unmodified chimney, smoke rises up the chimney propelled only by buoyancy—the heated gases from the fireplace being lighter than the ...
In darkness the resistance is around 1 MΩ, while when exposed to light from a properly ignited flame the resistance is much lower, around 75–300 Ω. Older oil burners were equipped with a primary control installed on the exhaust stack with a bimetallic heat sensing element protruding into the stack, such a control was referred to as a "stack ...
