Fog Light Switch problems of the 2015 GMC Acadia

My recent trip from connecticut to atlanta,GA and then to vero beach ,FL was driven at night. I found myself having trouble seeing any road sign hanging high, and most road signs in general unless I used my high beam lighting. I brought my car to the GMC dealership in both vero beach,FL and watertown, CT where I bought the car. It was found to have a very sharp cut off of light and with in the design tolerance. Both dealers have no clue as it is in GMC tolerance and there is no replacement light bulb for the light assembly. They both agree there is a design problem. I am now stuck with a new car that has bad lighting and will need additional lighting or get a new car from someone other than GMC. I did contact GMC and was told that there was not much they could do as it was per design. My car has no additional lighting, not even a fog light. Just received a call from GMC. The car is ok by its design, and as of now I have no more options.
