Pretty much anything can be made into a light using emitters.

As I wrote in the source as a comment: Poser Python does not allow access to everything. Or only in a very cumbersome way.
So there is nothing else than manual work (and the hope that there will be a corresponding function in Poser Python someday):

Use the menu item "Copy Object" in Poser to get a 1:1 copy. And then apply the mirror functions (that's the reason why I split this into single functions).
