Does anyone know how to edit a nif to light up both the front and back of character ?

This mod below is like facelight but it's an invisible ring to lighten up your character.SSLight Version 1.zip

 

 

This is how the nif looks like in nifscope but I was wondering if there was a way to have it illuminate both sides front/back rather than just the front.
