I have a friend who just bought a 2011 RT. It is his first so he doesn't know much about them. We were riding the other night and I noticed his headlights were in my opinion not working right. When he was behind me and went down a hill and changed angle to me they would turn blue and when we got on flat road they would go back to white. When he pulls up to a wall about 5 feet from it there is a blue line up about 3 1/2 feet. It is dark above the line and light below it. He told me that when he was behind me that the light was cut off in the middle of my back. It is so pronounced that when he goes down a hill he cannot see up till the starts up. Is that the way they are? If not what would cause it?
