Items you will need:

2x COB LED Ring 40mm (4.5 watts)
Wire (I use 22AWG)
4x Fastlock Piercing Connector
4x Bullet Connectors (2 male, 2 female)
Soldering iron and solder

Step 1: 3D Print Washer
Step 2: Solder wires to the LED Ring (The pads on the LED ring are tiny so it may be a bitch to solder them)
Step 3: Attach LED Ring to Washer 
Step 4: Run wires from LED through side faring
Step 5: Attach wires to turn signal wires behind headlight. I use bullet connectors so I can connect wires coming from LED to the wires coming from the turn signal so I can take the fairing off and on easily.

Notes:

Since the LED Ring is so bright you can just use solid color filaments instead of clear ones, I printed mine using solid orange and red, figuring out which color looks better. You can run resistors to lower the voltage going to the LEDs so they don't get so bright/hot but since I am just running these for the blinkers and they wont stay or for very long I run them without resistors.
