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.

How does light travel from a flashlight to a soild?
Light travels from a flashlight to a solid through the process of reflection and absorption. When the light beam hits the solid surface, some of it is absorbed, and some is reflected. The absorbed light energy can cause the atoms in the solid to vibrate, generating heat.
