The Nissan Xterra uses 9007 and 9004 bulb sizes for both high beam and low beam headlight applications. The replacement chart covers 2000 through 2015 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9007 bulb is the dominant headlight type across the Nissan Xterra lineup, serving as both the high beam and low beam bulb for the 2002-2015 model years.
The 9007 is a dual-filament halogen bulb operating at 12 volts with a wattage rating of 65W on the high beam filament and 55W on the low beam filament, housed in a PX29t base.
The 9004 bulb applies to the 2000-2001 Nissan Xterra for both high and low beam positions, and while it shares the same dual-filament halogen construction and 12-volt operating voltage as the 9007, its wattage differs at 65W/45W rather than 65W/55W.
Both the 9007 and 9004 are ANSI-standardized bulb types recognized in the United States and Canada, meaning they conform to defined performance and dimensional specifications within those markets.
Although the 9007 and 9004 share a similar physical profile and both use a P-type base, their base designations differ: the 9007 uses a PX29t base while the 9004 uses a P29t base. This distinction makes the two bulb types non-interchangeable despite their visual similarity.
The single-filament function of each beam position is handled within one dual-filament bulb on all listed Xterra model years, meaning one bulb per headlight assembly controls both high and low beam output rather than requiring separate bulbs for each function.
