I have some HID's in the factory 2011 housing which throw out a lot of light, but it goes everywhere and I get flashed every once in a while. They were done from the previous owner and I have been wanting new headlights since I got the truck. I almost bought some Anzo U-bars but the more research I did the less I wanted to cheap out.
I think I am going to end up getting a set made up by RSiWorks, it looks like he does amazing work. They aren't cheap but all you ever hear about lights is "you get what you pay for". I'll try and save some money somewhere else and pay for a good quality set.
