You need light to see.
Light may come from natural or man-made.
Natural light are the sun and the moon.
Man-made lights are those that use electricity and/or batteries to give off light. Examples are: light bulbs, flashlight, fluorescent lights.
Other man-made lights are candles, gas lamps and/or torches. Gas lamps and torches need fuel such as kerosene to produce fire.
