I had my windshield replaced with an M Lincoln glass at the dealership. Upon receiving the vehicle i noticed that when driving at night all lights are duplicated. The duplicated light eventutally merges with the actual light as you approach in distance. Multiple headlights on a highway are very disorienting and distracting making it hard to focus on driving. I have had the glass replaced a total of 4 times. All with the same problem. I was told there was defective glass that had been made however I have yet to get a piece of glass that is optically reasonable to drive at night. Wanted to report as I’m sure others have a similar problem.
