The turn signal that came on my older Unique did not have provisions for self canceling, so I had to take a different path.
Went to Radio Shack and bought a 12 volt piezo buzzer and connected it to the flasher. Cheap fix, albeit a little annoying when your sitting at a traffic light and listening to that noise...... but you won't forget to turn it off!! Just make sure to mount it somewhere so you can hear it over the pipes
