Light scene on movement

Hi. I’m making a game where the scene is dark and of course I want to see where I’m moving. I’m trying to do something like in this game Eyes: The Horror Game - Gameplay Walkthrough Part 1 - Mansion: Krasue (iOS, Android) - YouTube .As you can see the path is lighting but I don’t know how to do this. I’ve tried to add a point light to the character but the problem is that when I’m near a wall the light is too strong. How can I keep the same brightness and follow my character?
Thank you!
