Flashlight disable on box trigger

Hey, so I have a issue here with my Flashlight. The thing is that I now have a regular Pointlight as a flashlight attached to my skeletal mesh inside my Firstperson BP, now I want to be able to turn this flashlight off / on while walking on different trigger plates. I know how everything works with triggers etc, all I need to know is how do I link my pontlight from Firstperson BP into the Level BP?

Because I can't reach my Pointlight(Flashlight) inside the Level BP, and I can't reach my Triggerplates from my Firstperson BP

So how do these two connect?

Thanks in advance.
