double sticky tape on a stick through the bulb hole.
OMG.. I ride hugging the tank with my knees. This morning, while doing 55 mph, I felt an itch on my left knee and went to scratch it. As I pulled my knee far from the tank, I hear this buzzzzz noise that sounded like a bee flutterring from the front of the bike. It disappeared when I moved my knee back in. I tested it on my right knee and got the same sound. I tested both knees and there it is again! (Might have looked funny from behind). hahahaa. Anyway, anybody else notice the same?
