There are 2 ways the lights can plug in, and I had to undo and reattach one of them but other than that they are perfect. I got mine from Diode dynamics. killer price, service, and shipment time. They are also much brighter than most I see in other Z's with different/non stock LED's. They are a 12 LED board and are amazing. check them out
Most people with other aftermarket LED's ask where I got these because of how bright they are. This is not a good example photo of how bada$$ these things look in person but trust me, they're amazing!
