The function of the bulb in a flashlight is to generate some light when some electrical
current passes through it.
Note: That's actually the whole purpose of the flashlight. If there were no part of it
that generated any light, then you do just as well without the flashlight altogether.
The main function is mobile lighting. Some flashlight can do more than regular flashlight. Imalent flashlight can be adjusted by touch screen, and has red floodlight and UV light for different applications.

The bulb is the output. It is what illuminates the dark.
The first flashlight reflect beam from a flowerpot is USA. bulb is in flowerpot and battery is fixed at buttom of flowerpot.
Battery (chemical energy) goes to the wires (electrical energy) which goes to the light bulb (thermal and electromagnetic energy. In the bulb of a traditional flashlight, electric current energy is transformed to heat and then partially to light, when the temperature of the filament in the bulb is sufficient. In an LED type flashlight, little heat is produced and more of the electrical current energy is transformed into light.
The bulb produces the light.
The load of a flashlight is the bulb.

Need clarification please. The "it" you are referring to seeing, does that represent; A) the flashlight, B) the light from the flashlight, or C) "the speed of light"? Did you mean to imply that the flashlight was switched on? Is it an "old fashioned" bulb, an LED bulb, a laser light, or some other energy? Just wondering.
The average life-expectacy for a flashlight bulb is 1000-2000 hours. However, you can expand it's lifespand by reducing the tension or lenghtening the wire of the lamp.
