This central return duct, had a very large gap, so large in fact you could see the hallway, and the hallway light partialy lighted this area in the attic!!!
This is common with return ducts in new and old homes, Coastal Insulation can fix this!! This not only wastes energy, it makes your home uncomfortable!! Think about the pest that can enter and area with a large gap!? Keep Mickey at Disney where he belongs!!!
