Just wondered what you guys thought about them.
I'm all for making myself conspoicus. Wear a white helmet, bike has white fairings, and last summer got some orange LED things that mount near the axle to further attract attention.
Pulsing headlights, to me, are the visual equivalent of loud pipes. No question they are attention getters, but I find them annoying coming at me and even worse in my mirrors if they are following.
A non-riding friend likes them - he knows for sure it is a motorcycle coming at him.
