The 3 units I've been in here (2 current, 1 previous) have all had a light bulb in them. They are the larger units (10x10 or larger). The hallways are well lit also. Perhaps the smaller units do not have a light bulb.
Some large units do have lights in them and the hallways are very well lit. We also sell a small LED light you can mount to the wall in your unit.
