Custom lighting

Then maybe the light is very far below the object? Have you tried to zoom out a lot?

Otherwise if the light source was inside the object, you would just have to hide the object to see it...

Sometimes the appers of the light will not be seen because the far distance in between of light and object.

Indeed. Do you know you can move it? (with CTRL key pressed and the right mouse button pressed)
