Hello again Maru, thanks for answering :)
Sorry for my bad explanation, here i attach two animations:
1 Vray - as you can see when i create new lights, they appear only in "Rest", but when i stop and render again, they automatically appears as new nodes, even after deleting them
2 Corona - the difference here is that, every time that i need to add or delete lights i need to stop and use the script
sometimes i forgot that i create new lights or delete others, specially on big scenes, so, this could be very helpfull
