Another thing worth mentioning about those Anzo 211140s...
If you look closely at the pictures and compare them to the factory tails, you can see that the reverse light portion of the Anzo housings wraps all the way around the bottom of the lens instead of the little rectangular window on the factory housings. This makes the reverse lights much more effective by throwing light farther around the rear corners of the truck. You can see a lot better backing up at night if you're running some good bulbs.
EDIT - The reverse lights on the Anzos also line up almost perfectly with the bottom edge of the aluminum Chevrolet tail gate banners that some trucks have, which looks nice if you care about things like that.
