HID issues: Can I use aftermarket kit in my car with FACTORY HID?

Hey all, I have a 2007 Maxima SE with Factory hid. I'm having issues with my headlights. I replaced bulbs, they flickered a little bit and then didn't work anymore. Replaced ballast with no change. Have not replaced the ignitor.

I'm wondering if people have had success using a quality hid retrofit kit in a car that has the factory HIDs.

I don't drive this car much, but I've been several months with no headlights so I can't drive it at all at night. :-)

If you have recommendations for an HID kit for this car, weather in expensive or moderately expensive, let me know!
