WALLMART parking lot not so bright

Last evening, while I was driving into the parking lot of WALLMART.  I noticed it was creepy, and dark.  There were very few lights on. I thought about talking with the manager, but became hesitant as this is something that is very obvious, and has been getting worse as the months go by.  Anyone walking into, or out of the store at dark thirty could see that the lot is not fully engulfed with lights.
My fear is that this is an accident waiting to happen.  When a parking lot is lite haphazardly it becomes unsafe for anyone.  It is an accident waiting to happen.  
The parking lot almost  had a depressing feel to it.
I enjoy shopping at WALLMART, but will not go in the later evening because I do not feel it is safe.
 As I was exiting the lot, I realized how difficult it was to see the people walking to their vehicles.
I have lived here for almost a year, and the parking lot has progressively gotten darker and darker.  
What are your thoughts?
