pilot light
Always-burning gas flame
A pilot light is a small flame that burns continuously in a gas appliance, ready to ignite the main burner when needed: The pilot light on the water heater went out.
Most modern appliances use electronic ignition instead.
Figuratively, a pilot light is something that stays quietly active, ready to spark larger action: Her curiosity was a pilot light that never went out.
