The Nissan Pathfinder side marker utilizes 12961 and 168 bulb sizes for illumination across various production periods. Data for the specified lighting components covers the range from 1996 to 2019.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 168 bulb is the most frequently specified size across the Nissan Pathfinder side marker data. It is a T10 miniature wedge bulb rated at 12V and 4.9W, conforming to ANSI standards for the US and Canadian markets.
The 194 bulb shares the same T10 miniature wedge form factor as the 168 but draws less power at 3.78W. Both are ANSI-standardized and physically interchangeable in many housings, though wattage differences may affect brightness output.
The 12961 is a Philips part number rather than an ANSI designation. It is a T10 wedge bulb with a W2.1x9.5d base, rated at 12V and 5W, and is used in the front side marker position for the 2005-2006 Pathfinder and the rear side marker for the 2022-2023 Pathfinder.
The 7443 is a T20 dual-filament wedge bulb rated at 12V with a 21W high filament and a 5W low filament. Its larger T20 body is physically distinct from the T10 bulbs used in other Pathfinder side marker positions, making cross-substitution with 168, 194, or 12961 bulbs incompatible.
The 1157 bulb uses a BAY15d bayonet base rather than a wedge-style base. This base type is mechanically incompatible with the wedge sockets used by all other bulbs in these specifications, and it is exclusive to the rear side marker on the 1987-1994 Pathfinder.
The 1999 Nissan Pathfinder front side marker has two distinct bulb fitments within the same model year. Early production units use a 168 bulb, while late production units use a 7443 bulb, indicating a mid-year running change that requires production date verification before replacement.
The front side marker specification for the 2000-2004 Pathfinder calls for the 7443, a dual-filament T20 bulb. This contrasts with the single-filament T10 bulbs specified for earlier and later model years, reflecting a change in the front marker lamp assembly design during that generation.
The rear side marker for the 2013 and 2015-2020 Pathfinder uses the 168 bulb, while the 2022-2023 rear side marker uses the 12961. Although both are T10 wedge bulbs with the same W2.1x9.5d base type, they carry different wattage ratings and originate from different standardization systems.
The front side marker specifications span from 1987 to 2020, while the rear side marker data covers 1987-1994 and then 2013-2023, with no rear side marker entries present for the years between those two ranges.
Across both front and rear positions, three distinct base types appear in the Pathfinder side marker data: the T10 wedge base shared by the 168, 194, and 12961 bulbs; the T20 wedge base used by the 7443; and the BAY15d bayonet base used by the 1157. Substituting a bulb with a different base type is not physically possible without modifying the socket.
