Conect first player character with level blueprint

Hi All, I hope you could help.

I’m currently working on a simple screen touch button for mobile applications.
Basically, I have 2 buttons.
Button 1: to move forward which is perfectly working.
Button 2: to toggle on/off lights. I have printed a string in the viewport to check if the button is working (working fine) however I need to know how to link the lights from the level blueprint to the first person character blueprint.

attached the screenshots of:

  1. widget blueprint
  2. first person character blueprint
  3. level blueprint
  4. function inside of level blueprint

I hope someone can help

Many thanks

I think you’ll need to look at using event dispatchers:
