Lol yea it's only down the back. The only thing I don't like about the light housing is that if u have the tailgate down there is a significant gap between the light housing and the bed more than the stock housing but with the gate closed you can not tell at all. I will take a pic of what I am talking about later today before I head to work.
hmm... thanks for the heads up and I wait for the pics. Definitely something to take into consideration
