pilot lights
Gas appliance igniters
Pilot lights are small flames that burn continuously in gas appliances, ready to ignite the main burner when needed.
Found in furnaces, water heaters, and stoves, they eliminate the need for manual lighting each time.
Many modern appliances have replaced pilot lights with electronic ignition to save energy.
Figuratively, a pilot light is anything that stays lit in readiness: Her curiosity was a pilot light that never went out.
