Nissan Pathfinder Trunk Bulb Size

Additional Notes

• The Nissan Pathfinder trunk uses two distinct festoon bulb sizes across its model years: the DE3423 for 2022-2024 and the DE3175 for 1996-2004.
• Both the DE3423 and DE3175 are ANSI-standard festoon bulbs rated at 12V, making them compatible with the standard 12-volt electrical systems found in North American market vehicles.
• A festoon bulb is a cylindrical lamp that makes contact at both ends via flat or spring-loaded end caps rather than a side base or pin configuration, which determines how the bulb seats within the fixture.
• The DE3423 measures 41mm in length, while the DE3175 measures 31mm. These two bulbs are not interchangeable despite sharing the same festoon contact style and voltage rating, as the 10mm difference in length affects fitment within the trunk lamp housing.
• Both bulb types carry ANSI designations valid for the US and Canadian markets, meaning they conform to standardized performance and physical specifications recognized across North American automotive applications.
• The 1997 model year Nissan Pathfinder carries a production date qualifier, specifying the DE3175 for vehicles built from July 1996 through December 1998, which indicates a mid-cycle production window rather than a full calendar year fitment.
• The 1996 model year entry specifies the DE3175 for vehicles produced from October 1995 onward, reflecting that the 1996 model year production began before the calendar year started.
