I have the Givi lighting kit for a top case for my other bike. It's pretty easy to install if you have a few tools around, and super easy to take the case on and off. Like the other guy said, the electrical contacts are on the mounting plate so you just take the case on and off as if there were no lights. It's cool. The wires that come with it are pretty lame though. I had to replace them with a heavier gauge wire so they wouldn't keep breaking. I recommend the kit.
