pilot light

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 source is necessary, as in when lighting a large burner.
The term "pilot light" is also used occasionally for an electrical indicator light that illuminates to show that electrical power is available, or that an electrical device is operating. Such indicators were originally incandescent lamps or neon lamps, but now are usually LEDs.

    Boiler pilot light won't stay lit after meter change

    We just had our meters changed from prepayment to smart meters. The boiler was lit after with no leaks, but has subsequently gone out and won't stay lit anymore. There is still a good gas supply to the cooker so I don't think it's a supply issue. Any ideas???
