Pilot Light (Fallout 3)

The pilot light is a miscellaneous item in Fallout 3.

Gameplay
A pilot light, as its name suggests, uses a small gas flame to ignite a larger source of heat, such as in a gas oven.

Uses

 * One is needed in the creation of a Shishkebab and it serves as Rock-It Launcher ammunition.
 * In the Tranquility Lane simulation, loosening the pilot light in Martha Simpson's oven and asking her to start it will result in a gas explosion, killing her.

Locations
They're frequently found in ovens (found in many abandoned houses, for instance in Minefield), or in workshops. A pilot light can be obtained early in the game by searching through Silver's stove inside her house in Springvale, in the Super-Duper Mart in the back room, or in the RobCo facility.
 * 11 in the broken bow.
 * Seven in the Robot Repair Center.
 * Five in Hubris Comic's utility tunnels.
 * Four in Lucky's.
 * Four in RobCo facility's office and cafetaria.
