Unity light going through walls.
That s why shadows exist.
The layers are the dropdown box in the upper right of the inspector.

Light passing through walls 1.
You have a point light source behind some walls.
Set the point light s baking property to mixed or baked then bake your lighting data using the lighting tab.

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