Light don't turn on after repairing the electrical panel

Thanks, it works ! But for one light, not more than one. I tried with the custom events, and to call the event for the point light, I tried with a “Get actor of class”. I tried first with a “Cast to [name of my blueprint with the pointlight]”, but my problem is that I usually doesn’t know what to put in the object of the cast, as there’s nothing like “Other actor” or else, like there’s on actor begin overlap, for example, on the custom event… I saw that there was “Get all actors of class”, but it have an array. I created a variable as a reference of my pointlight, and put it in array, but it seem it doesn’t see it when I try to plug it in the get all actors…
