Nissan Pathfinder Headlight Bulb Size

Additional Notes

• The 9007 bulb is a dual-filament type that serves both high beam and low beam functions within a single housing, and the Nissan Pathfinder used this bulb for both beam positions across the 2005-2012 model years.
• The 9004 bulb is also a dual-filament design, functioning as both the high beam and low beam source in a single unit. The Pathfinder relied on this bulb type for both beam positions from 1987-1998, making it the longest-running bulb type in these specifications.
• The 9003 bulb, internationally designated as H4, is a dual-filament halogen bulb compatible with both beam functions. The Pathfinder used it for both high and low beam positions across the 2000-2004 model years.
• The 1999 Pathfinder carries a mid-year production change, with early model units specifying the 9004 bulb for both beam positions and late model units switching to the 9003 for both positions. This split-year fitment requires production date verification before purchasing a replacement.
• From 2013-2020, the Pathfinder moved to a separated beam system, with the high beam and low beam each requiring a distinct bulb type rather than a shared dual-filament unit.
• The H9 bulb is a single-filament halogen type rated at 65 watts, used exclusively for the high beam position on the 2017-2020 Pathfinder. It uses a PGJ19-5 base and is not interchangeable with the H11 low beam bulb used alongside it, despite both belonging to the same PGJ19 base family.
• The H11 bulb is a single-filament halogen type rated at 55 watts with a PGJ19-2 base, designated for the low beam position on the 2013-2020 Pathfinder. The 2017-2020 entries specify this bulb under a "With Halogen Capsule Headlamps" condition, indicating that alternative headlamp configurations existed for those model years.
• The 9005 bulb is a single-filament halogen type rated at 65 watts, used solely for the high beam position on the 2013-2016 Pathfinder. It is not listed for the low beam position in any model year covered by these specifications.
• The 9004 and 9007 bulbs are not interchangeable with each other despite both being dual-filament types. They differ in base configuration and wattage ratings, with the 9004 operating at 45/65 watts and the 9007 at 55/65 watts for low and high beams respectively.
• The 9003 and 9007 bulbs are also non-interchangeable despite both covering dual-beam functions. The 9003 uses a P43t base while the 9007 uses a PX29t base, meaning the Pathfinder's 2005-2012 and 2000-2004 headlamp housings accept physically distinct connectors.
