Price isn't the main problem... getting the lights to the US is the problem. These are big bulky glass lights that come attached with HID ballasts, auto leveling system, city lights... heavy and bulky!!
Nissan Terrano Regulus lights are a direct bolt on, plug-n-play for any 97-99 QX4 (with glass headlights). To fit to a 99.5-00 (which comes with plastic headlights) like I did, it requires cutting up the radiator support and changing the light sockets from 9003 to 9004.
You can also convert your front end to 2001-2004 HID.... you will have to do some work to make the lights fit but its been done before here on Nico...
Or you can do a projector retrofit
