I thought about the light issues as well.....
I have had several thoughts, 1. just add a light and turns signals to the box, should be a fairly simple plug addition. 2. lower or remove the rack and mount the trunk in it's place then put the factory light and signals on the box. I am leaning toward the first, I want to leave the bike as unmolested as possible
I am going to look for a lock tommorrow
