I've put about 30,000 miles on my Givi V46 brake light kit and never had a problem with it.Resurrecting this thread from the dead as I'm thinking about extra lights. I now have a Givi box and am wondering if this IS a real problem. If it is, I'll just get a light up license plate or bracket or something.Vibration makes them wear quickly and fail pretty early. Contact deterioration and general wear were considerable on mine in less than 15K. My brake light on my 04 was flakey, flashed a lot, and often didn't work at all. If you have this kit on your bike now, light up your brake lights and shake the topcase. It might be as lousy as mine was.

What I don't like about the design is that the contact point housing inside the case is held on by gravity. I have taken something out of my top case many times and pulled the contact housing out by accident.
I liked having the kit on my V46 so much I ordered one for my E55.
Installation instructions were indeed vague; however after the hell I went through putting the side racks on my FZ6 it seemed easy by comparison :\
