For the 2011 Nissan Xterra, both the low-beam and high-beam headlights use a 9007 bulb. The supplied fitment data does not indicate a separate bulb for different headlight types or configurations, so use 9007 for either headlight function.
Fog light fitment is listed with two LED options: H11 LED and H16 LED. Confirm which option matches your existing fog-light housing before ordering. Other useful exterior bulb sizes include 3457A for the front turn signals and parking lights, 194NA for the front side markers, and 3157A for the rear side markers.
