We finally installed my kit(my brother and I), price was$539 with shipping, this kit is low beam only and completely plug and play, this kit has one harness that plugs the whole kit into one side of my OEM plug. I noticed a huge difference between my 6000k and the stock 4100k or 4300k on Acura, BMW, Lexus, etc, my light out put is more bluer and brighter on anything they shine on.I am very satisfied with quality of this product and the final results, I took pictures with a 3.1 mega pixel digital camera, I'll try to post them later.
