Honda Passport high beam headlight bulbs use 9005, 9003, or 9004 sizes, while low beam bulbs require 9003 or 9004 sizes depending on model year. The replacement bulb size chart covers 1994 through 2023 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9005 bulb is a single-filament halogen type operating at 12V and 65W, fitted with a P20d base. Because it carries only one filament, it serves exclusively as a dedicated high beam bulb rather than a combined high/low beam unit.
The Honda Passport uses the 9005 for the high beam headlight across the 2019-2021 and 2023 model years, with the 2019 and 2020 entries specifying that this fitment applies to vehicles equipped with Halogen Capsule Headlamps.
The 9003 is a dual-filament halogen bulb with a P43t base, rated at 12V and 60W for high beam and 55W for low beam. Its dual-filament design allows a single bulb to handle both beam functions within one housing.
The 9004 is also a dual-filament halogen bulb, but it uses a P29t base and carries a higher wattage split of 65W for high beam and 45W for low beam at 12V. The P29t base is physically distinct from the P43t base of the 9003, making the two types non-interchangeable.
For the Honda Passport 2000-2002, the 9003 serves as both the high beam and low beam bulb, meaning a single bulb type covers both functions in those model years.
The 9004 appears across the 1994-1999 model years for both high beam and low beam positions, again as a single dual-filament bulb handling both functions.
The base type is a critical fitment factor across these three bulb standards. The P20d, P43t, and P29t bases are each unique in their connector and retention design, so substituting one bulb type for another is not physically possible without modification.
All three bulb types listed, the 9005, 9003, and 9004, conform to ANSI standards recognized in both the United States and Canada, indicating standardized electrical and photometric performance requirements for each type.
The wattage difference between the 9003 and 9004 on the low beam filament is notable: the 9003 draws 55W while the 9004 draws only 45W, despite the 9004 drawing more power on the high beam filament. This reflects differing design priorities between the two standards.
The high beam headlight position on the Honda Passport has used three distinct bulb types across its production span, specifically the 9004, 9003, and 9005, each requiring a different base and carrying different electrical characteristics.
