There isn't a Reallusion specific tutorial on lights in 3DS Max but there is a nice tutorial that deals with self illumination and glow which gives some nice examples.
You can check it out in the Developers section if you haven't already. It is called Working with materials and shaders in iClone. For actual tutorials on lights I have found the Max tutorials themselves are very helpful as well.
There is also an iClone tutorial that deals with lights. Have you looked at this one?
