Well at least you guys have a sense of humor. I was riding tiday and seen two bikes with mirrors on the top corners of the fairing yesterday i saw one. I was trying to find it in the web but can't find anything. The picture shows the spot I'm talking about.
What you are probably seeing are tweeters. Hogtunes has a tweeter bar that locates two tweeters in the spot you are describing. Other companies have made tweeters that bolt there. Never saw any mirrors there.
I have seen tweeters in the corners but they were almost right next to gages, I don't remember them being up in the corners. Looking at my fairing i don't even see how to would a functional mirror in that spot. You're probably right, i bet the sun made them look like mirrors.. See no drugs, just confusion
