This kit is nearly brand new, I picked it up from a fellow TheNewX.org member, I changed my mind the next day and wanted to go a different route. It's a 6000k kit for the 9007 style bulbs. This is a PLUG AND PLAY kit, no modifications are needed to get this kit working. I'm asking $100 since that is what I paid, plus shipping, I'm looking to get rid of it quick as I have some things that I need to take care of.
