This my third time I have purchased a Billy Tail light. I had them on 2 other BMW’s. In this day and age of distracted drivers you need every advantage as a motorcyclist. This product combined with a cambus electrical distribution accessory like an Xcam or whatever is a necessary item to keep you as safe as possible. The Billy really lights up you tail and I’m sure it’s distracting to the driver behind you especially if you set it up using the California flash cycle. You may wear Hi Vis clothing but I believe this is a cheap and better way to be seen.
