Motorcycle: 2007 Kawasaki ZZR600IMPORTANT! When installing the blinkers it is equipped with 2 positive wires for the left and right blinker. It’s easy, just splice the left light to the left blinker and right light to the right blinker, if it does not work then try the other wire on the bike. It is ground back through the brake system wires.Review: I am very impressed with this product. I ordered it for a great price and it got here within a week from Hong Kong! Very good timing. When I opened the box I was very impressed with the quality of the plastic, it was all very hard and high quality plastic and the tint is just perfect. It was all neatly wired and I was happy.The hardest part about installing this product is removing the fairing. For the brake light it plugged in but the bikes adapter was different so I just taped them together, no big deal. The blinkers are 1 wire each and the light is internally ground for those wires. Splice the lights wire into the bikes blinker positive wire and it is done. It’s that simple so don’t stress out about it like me.These lights are very bright, hard and high quality and they fit perfectly on my bike. Last but not least, they look amazing. 5 out of 5 stars easy like.
