How to hide/show built light?

So, I have a Generator CPP Script. After I push button, it must set the Visibility of every APointLight object on level. It, actually does, but there’s still pre-built light on walls next to every APointLight object. Here’s how it looks like:


(Visible “Lamp”)

(Invisible “Lamp”. but still some light)

So my question is how to hide and show it again from the code, if I have pointer to every “Lamp”?
Any ideas?
