why can I only see through half the windshield when headlights are on at night

For a 2014, I would take it back to the dealer. Possible headlight misalignment?

I have the same issue with my 2015 Corolla. The top part of the windshield seems is darker, then lowers down the windshield while driving. It's very distracting.

My father is having the same problem. Please report it to https://www- odi.nhtsa.dot.gov/ivoq/. My father believes it's due to the high intensity lights and strip they put on the light itself. When he goes down hill at night the windshield goes dark and is very scary to drive. Several others are having same issues but it's not being reported enough. He has a Toyota Corolla S 2015. Dealer was no help.

I am having an identical problem with my new 2016 Ford edge. Very Scarry. Took it back twice and the dealership and they adjusted the headlights each time, but this has not corrected the shadow problem. I do intend to complain direct to Ford since the dealership has no answers. Anyone else out there with a Ford edge that you are very weary to drive at night?

Our new Kia does the same thing, my sister in laws Toyota is worse. It is the high position of the lights, not the windshield itself.
