For the 2002 Nissan Pathfinder, the low-beam and high-beam headlights both use a 9003 bulb. The supplied fitment data does not indicate a separate bulb size or a projector/non-projector headlight distinction, so confirm the original bulb and housing before ordering.
Front fog lights may use either an H3 or H3C bulb. Other exterior lighting includes a 7443 front turn signal and parking light, a 7443A front side marker, and a 1156A rear turn signal. The brake and tail lights use 7443R bulbs, while the reverse lights use 921 bulbs.
The center stop light and license-plate light may use either 168 or 917 bulbs. Interior and cargo-area lighting share the DE3175 bulb, used for both the dome and trunk lights. Because several positions have listed alternatives, compare the installed bulb or socket with these sizes before purchasing replacements.
