I got two sets of HID lights, the whole system, they are just plug and play. The first set is 12,000k /9005 kit. and the second set is 10,000k/ 9006 kit. I had them on my 05 sierra z71 for like two weeks, they looked great. I took them off for the reason that i traded in the z for something else. Im asking for 340.00 plus shipping for both. They were for the low and fogs, but they also fit the high beam. They also fit several other trucks, check sylvania.com for the fit guide. Email if you have any questions. Muddonthetires03@aol.com
