I am in the same situation... Only I have a 2001 QX4. Dealer by me in St. Louis wants $299.99 per bulb!!! Absolutely insane... Needless to say I didn't, and I hope you didn't, get it from the dealer.
Here is what I did find out, however. Supposedly this "Akinaboy" on ebay is the place to go. I just found his ebay store tonight, and found a wealth of information on the matter. Let alone, the price for the bulbs are only like $80 for the pair!

It seems that our models use the HID-D2R bulb for low-beam. Check this site to make sure it's the same for 02 as 01.

I can't seem to find much on installation, which I'm confident I can do without. My main concern is how to correctly aim the headlights.
Let me know what you have found out. Good luck man
