A good friend melted a piece of his synthetic jacket on his Bonneville headlight. I had pulled up on my Rocket, removed my First Gear jacket and thrown it over windscreen where it also covered the headlight. A mutual rider friend asked if I was trying to set fire to my jacket and when I gave him the ?? look he told me what happened. I grabbed my jacket, felt the lens and that thing was very hot. Never again. I got to install the LED light that is sitting on my work bench.
