pilot light

We can use a ground-service cable; rig a pilot light on it, and kick it out, as soon as they get in close.

One of the functions of a pilot light is to prevent people from being burnt in case of an explosion in the oven.

“I saw a man putting in a little pilot light for the oven, to-day,” said Mrs. Morton.

Most stoves are constructed so that there is a pilot light for the oven.

Sometimes when the gas pressure is low, the pilot light will go out.
