Lights are on when a circuit (a path for electricity to flow through) is complete, and light is produced when electricity passes through the bulb because the material is energized by electricity, causing it to give off electromagnetic radiation. Most of the EM radiation is in the form of visible light, but some is in infrared which is why light bulbs (especially incandescent) get hot. When you turn off a switch, the circuit is broken at the switch, so electricity does not flow through the bulb.
