Piece of cake to wire. Put them on both the front and rear. Installed one 10 ohm 10 watt resistor across the rears on each side to make them blink normal.
Resistors from Radio Shack...$1.99.
Labor to install... free.
One off installation... priceless!
Yep it's rash, bummer, the PO must have laid it down. Sticker covers the scrape on the swing arm, going to clean off the rest of the teeth so they look the same.
