A flash light generally makes light using a light bulb, which contains a filament. The filament is typically made from tungsten. It is very thin, but capable of withstanding extremely high temperatures. Electricity, from an internal power source, is passed through the filament. The filament has a resistance, so the current creates a very large heat in the wire. Because the wire is so thin, it heats up very quickly, and this excess energy is given out as light, and heat.
