The turn signals on that green bike are from the Custom Chrome V-Twin parts catalogue, atleast they look like they are.. They run about $35 for the pair. They also come with red lenses if you want to go all red in the rear of the bike. He prob. has it wired so the amber lights are his turn signals , and the side mout light is his brake.
In the pic below , you can see my setup. Similar , but my small bullet lights act as marker/running lights , as well as brake lights. My bike no longer has turn signals. I wanted as many brake lights to help keep those Chicago drivers off my ass !!
Bar-end mirrors are readily available , from any decent metric shop. You can even go to a American v-twin shop , and see what they can order you up. Carpy does have some cool stuff , but if you look around , their are many other great places to go for parts. V-Twin shops have lots of parts that can be adapted to these bikes , especially in the lighting department, as well as tires , suspension , etc...Another cool thing is that you can make allot of " Cafe" style parts for your bike yourself. Even something as simple as high temp ceramic paint can make a dull motor look better....
