`03 has factory HID, no? Or did you specifically want projectors? As for street legal, unless your Maxima came with the factory HID I don't think any of the HID retrofits are ever going to be street legal.
2000-2001 didn't come with HID's.. 2002-2003 came stock with HID's.. So if you have a 2000-2001 and want HID's.. buy 2002-2003 complete headlamps and wire them in.. Alot of 5th gen guys do that.. Pricey.. but sexy imo.
