In a few cases, you might see the light as well. Do you know why that is so? When the electricity converts into heat energy and reaches 1000F, you’ll see visible light. 

This is the phenomenon behind the lighting of the bulb. The heat energy formed as a result of the electrical flow is what makes a bulb light.
