One question. What Yamaha housings do you have? They made two driving light housings. One for the RSV and the other for the rest of the field. The RSV housing has the horizonal bolt and the others have a vertical bolt. I have the bezel with horizonal bolt on mine. The LED light sets in the bucket and the foam spacer in the bezel to hold everything tight. If you have the bezel with the vertical bolt you will have problems getting things lined up.
