I purchased a great 05 Road king last summer and the guy I purchased it from gave me headlamp & directional lamp fairings. I tried installing them annd when I put them on they were able to spin, someone suggested a dab of silicone to hold them in place. Is that the solution?

 

I'm not sure what you mean by fairings. Possibly visors? If so I guess you could use silicone to hold them on. That way when you get tired of them you can just yank them off.

 

I had'em on my Heritage anf the trim ring screw supplied the tension to hold them in place

 

That's how my buddy does it on his Yammy.

 

Some come with O-rings to hold them tight. You might be missing parts.
