Is this the correct way to set up a light_source and attached object?

// Sun
light_source
{
	Source_Location
	rgb light_color
	looks_like
	{
		sphere
		{
			Source_Location, Source_Radius
			texture
			{
				pigment {color rgb light_color}
				finish
				{
					emission	1
					ambient		0
					diffuse		0
				}
			}
		}
	}
	parallel
}

Note that the light source and object are both located at 
Source_Location. I'm not sure how to test whether I'm doing it right or 
wrong.
