There are more pictues in the Trailer porn thread but here are a few details of the lighting to help out.
I posted a link somewhere to the ebay store I bought them through. I like to buy local, but I could find nothing low profile like that here. Pacific steel (our local metal fab supply house) did have the button lights.
all the wiring runs through the box tubing and the lights each require a 5/8" hole for the long lights and a 3/4" hole for the button lights.
The back up lights also came from the ebay store and are super bright but I haven't really gotten to use them yet. I can't wait for a late night take out
