You can use a Get All Actors Of Class node and a ForEachLoop to turn off every light when the player uses the switch.

While Get All Actors of Class Node works.

Why not get references for all the lights, put them into an array, and then use that array to turn off all the lights?

The reason being is that Get All Actors of Class node is high in performance cost.
