This was the easiest mod I have ever done on a Spyder. The plug-and-play feature is a bonus. Ver good installation instructions and the information on how to stop hyperflash was really helpful. It took me literally 30 minutes to install both, but I must say that in hindsight, I wish I had placed them on the top of the mirrors closer to the rider rather than on the front of the mirrors, which for me, makes them harder to see. But overall I am very happy with the product, and I highly recommend that anyone with an RT buy and install them. You will be glad you did!
