You seen how much it is to replace a bosch headlamp? I still need my kidneys so could not pay for one that way. Not that my headlamp has been hit By anything. Yet! our roads are crap. there is so much gravel and stuff that gets flung up at me as I ride along. So again I went to A.M.H.P and bought one of their headlamp protectors. Again very simple to install as per their instructions and supplied cleaning wipe. You get the super sticky, super grip together 3m Dual Lock fasteners. This time I was able to fit the protector so it is straight. I have a crocked eye and everything I mount or cut ends up not straight. This time I had the lens to guide me.
