I started my led rear turn signal over the weekend. I'm putting mine on the passenger pegs. Will take pics when done. If you're wiring more than one LEDs, you won't need any resistors depending on how many you will connect in series. It's quite simple actually, for a 2.0V rated LEDs, I used 5 LED's connected in series and no resistor required (2.0V X 5 = 10V). That's close enough to 12V so it wouldn't fry.
