    Hi,
    I do not use vray but I think that if you use the Script Log, when you choose the vray tag, you will see the CallCommand ID.

    the call command comes up as c4d.CallCommand(100004788) and when I run that nothing happens. no light  tag is created. :(

    hi,
    sorry my mistake , this is a tag so callcommand not working.

    Here I will show you how you should work when scripting:

    1- Will we find the Vray light tag ID:
    add a light to your scene;
    add to it a Vray light tag
    Select the light

    import c4d
    from c4d import gui
    #Welcome to the world of Python
      
    def main() :
        mydoc = c4d.documents.GetActiveDocument()    
        myobj = doc.GetActiveObject()
        print myobj.GetTags()    
        
    if __name__=='__main__':
        main()
    

    In my case, I added Xpresso tag and I get:
    [<c4d.modules.graphview.XPressoTag object called 'XPresso/XPresso' with ID 1001149 at 0x10C249A0>]

    2- Now you have the ID, so we will call it myID:
    add a new light and select it:

    import c4d
    from c4d import gui
    #Welcome to the world of Python
      
    def main() :
        myID = (put here the ID returned by the 1 print)
        mydoc = c4d.documents.GetActiveDocument()    
        myobj = doc.GetActiveObject()
        if myobj==None or myobj.GetType() != c4d.Olight:
           gui.MessageDialog('Select a Light!')
           return 
        mytag = c4d.BaseTag(myID)
        myobj.InsertTag(mytag, None)
        c4d.EventAdd()
        
    if __name__=='__main__':
        main()

    On a side note: Built-in tags have a symbol name in the c4d module which should be preferred over
    using integer IDs. Eg c4d.Texpresso

    You can also use BaseObject.MakeTag() instead of the BaseTag() and BaseObject.InsertTag() construct.

    Best,
