My bike is a 13. I want to replace the headlight with an LED light. From what I'm seeing you have to remove the fairing to do the job. However I did see a video where you can remove the front bezel and just replace the lights. The lights I have seen all come with a mounting plate that gets mounted to the fairing. My question is. Why must you use the mounting plate? And why can't you just remove the lights from the existing housing by removing the 4 screws that hold it in and install the new lights.
