The standard headlight on my '06 Dyna Super Glide started vibrating up and down; I could see the oscillations on the reflective road signs ahead. At first, it didn't bother me, but it became worse and worse.
It appeared that the rivets had loosened on the headlight housing, allowing this to happen. Oddly, sitting at a stop light it vibrates worse when I apply the front brake, and lessens with I release the brake.
Ironically, I find that this vibration is a safety factor, and I am reluctant to fix it...cars really notice me. I believe that one person thought I was a COP, and pulled over.
My son and I put some silicon sealant between the rivits as a, sort of "shim" and it reduced the vibration; but it is still there.
A Harley replacement part is of course, out of sight price wise...but a Kuryakyn part is more reasonable.
It is NOT keeping me from riding. Anyone had this problem???
