I got these. Not much is going to change the direction of the lights unless you buy a new third brake light housing, but if you just throw more light in there it'll be better. The link from Bo3liwe is $40 for 1 pair.
I also eventually plan on running an LED strip on the underside of the bed rails wired to a constant switch. Had that on my old truck for 5 years, and worked great.
