You can see the wire better here.
and from the old one.
The wire comes through the trailer wall in exactly the same place. The pipe flange has 4 bolts holes and we threaded the wiring through one of those bolt holes. The other three are for the screws that hold the flange to the wall.
The bearing is just a simple brass bearing that is press fit into the central hole in the flange. We had to heat the flange, and still had to force the bearing in. The light is actually bolted to the bearing with the shoulder bolt (not the one on the list though, we ended up finding another one), which allows the swivel motion. The only waterproofing needed is the wall where the wiring comes through and where the screws are used to hold the flange.
Beth is working on a sketchup cross section to give you a better idea of how it goes together.
