Blueprint glow stick / light system on/of

hello guys,

To need a help for two things in the scene I’m doing the video;

1 - glow sticks (light green that appears) need to make a system that the player plays this light to illuminate the scene.

2 - boxes need to do a light system on / off type of Alan Wake, who played should understand more or less how to go to the player by connecting the boxes.
If anyone knows of any tutorial. Thank you

NOTE: I removed the shadows of the scene at the time of the video, because it is too heavy for my machine, the graphics are much better with shadow enabled ok, I updating the PC coming soon lol.
