Let's add one of these virtual lights to our Scene so that we can see our objects a bit better.

A new directional light is added to the Scene. The icon looks like a little yellow sun. When the light is selected (as it is now), a tube of yellow rays shoots out from it. That tube shows us which way the light is pointing.

Make sure that Scene lighting is turned on by clicking on the little sunshine-looking icon at the top of your Scene view.
