Inputs-battery/electrical energy-this powers the light so it turns on. Without it, the flashlight will not work.

-light bulb/light energy-this makes the shine work and produces the light. Without it, there would be no light from the flashlight

-the on/off button/electrical circuit-this turns the system on and off. It allows the circuit to be opened and closed and prohibits the battery from running out. Without it, the flashlight would be on all of the time and the battery would run out.

-casing-this protects the battery and the light from water damage or other damage. Without it, the flashlight could be damaged, it would be harder to use, and the person using the flashlight might get an electrical shock.

Outputs-light/light energy
