When I first got my X (end of 2002), like about month or 2 later, I installed piaa's replacement bulbs, so I have a pair of Xterra OEM 9007 bulbs (headlights) and Xterra OEM H3 bulbs (fog lights). The headlights were used for about a month or two, but the fog's are pretty much brand new. They are both in the Piaa Cases. If anyones interested in purchasing them let me know, I can also send you pics by email.
