This solution works in other engines like unity and ue4.
Unity light passing through walls.
You have a point light source behind some walls.

Create a unity primitive cube plane etc sized similarly to your wall remove its collider and in the mesh.
Shadows are the obvious answer however i assume you are using lite and that s not an option.

You can simulate this in shaders or use raycasts to see if the light is behind a wall.
