There are actually 2 different versions.
One fitting the 2000-2001 Xterras an another for the 2002-2004 Xterras.
Lights not included. Lights shown are the KC Daylighters. Ideal for this application.


As you can see from this next image is that the cage actually extends the useful length of the OEM roof rack.

2002-2004 version seen below, same lights.


Thanks to Tim and Adam for the use of their rigs for these products development.
I still owe you one Tim.
