7) Mount the light sockets onto the posts using your machine screws and hardware. They??ll only really fit one way; you have to picture the post being installed in the hood in such a way that the corners point to each other and edges are parallel. I know that wording sounds really confusing so try to look at the jpegs Then make sure the 90 degree bracket on the light socket goes inside the post, not outside. Drill two holes near where you??ll be mounting each post. These holes will be for the rubber grommets, in order to determine what size whole you will need to drill, look at the package from the grommets, and drill a hole equal to the outer diameter. Stuff the grommets into the holes.
