I bought a set of HD Chrome Switch housings. I also bought a set of Chrome Switch covers. While out on a ride, I noticed the Switch cover for the headlight High/Dim was missing. What the hell. I looked down and the cap was between my leg and the gas tank. I gave my wife the cover for safe keeping. When I got home, I installed it again. It has a distinct snap when installed. Sounded good to me. Well, while on another 2 day ride, I noticed the cover was gone again. This time I couldn't find it. Has anyone else have any similar issue with this?
