HI Alex,
There are two ways that I would like to suggest.
The first one works just by making the light object a clone (Set the Cloner>Transform>Color: black!)
The second way works by just getting the information from the Cloner via Data Node. Perhaps place a Range Mapper between the nodes (data and light) to have more control with the Spline Interface.

I guess _03.c4d or _04.c4d is what you are looking for.
Let me know if there is something else, I’m happy to look into it.
Cheers
