I have a 35W 4300K H4 HID bi-xenon kit I don't need. The ballasts are hoen (www.hoen-usa.com) ballasts that were used for about a month on my old vehicle before selling it. They are high quality expensive digital ballasts. The bulbs and relay are from Kensun and are brand new and have never been installed. I ordered a kit from xenondepot and was going to save these parts for spares but I might as well sell them if someone wants them. $45 shipped obo. Just so you know, the hoen kits are $150 and the bulbs were $33 shipped, so I am essentially selling the almost new ballasts with a 3 year warranty for nothing as it will cost me at least $10 to ship. Anyhow, everything you need is included and good directions can be found on this site for install.
