The Lincoln Navigator tail light uses bulb sizes 3157, 4057, 4157, 916, and 2458 according to the provided data. Information for the specified components covers the range from 1998 through 2014.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Lincoln Navigator lower tail light draws from three dual-filament wedge bulb types across its model range: the 3157, 4057, and 4157. All three share the same T25 wedge form factor, operate at 12V, and carry a 27W/7W dual-filament rating, meaning the higher wattage serves the brake or turn function while the lower wattage serves the running light function.
Although the 3157, 4057, and 4157 are physically similar T25 wedge bulbs with identical wattage ratings, they are distinct ANSI part numbers and are not universally interchangeable. Each position in the specifications calls for a specific type, and substituting one for another without verifying socket and keying compatibility may result in an improper fit.
The Lincoln Navigator upper tail light uses single-filament wedge bulbs exclusively. The 906 (T10, 8W) and 916 (T15, 18W) types are both single-filament designs, which reflects the upper position's role as a lower-intensity lamp rather than a dual-function brake and running light.
The 906 and 916 bulbs differ in both body size and wattage. The 906 is a T10 miniature wedge rated at 8W, while the 916 is a T15 wedge rated at 18W. These two types are not interchangeable due to their differing physical sizes and power draws.
For the Lincoln Navigator (2007-2014), the lower tail light position specifies the 4057 bulb for model years 2007-2010 and transitions to the 3157 for 2011-2014, indicating a socket or assembly change between those production periods.
The 2005 Lincoln Navigator lower tail light carries a production-date-dependent specification. Units produced up to 11/29/2004 use the 3157, while units produced from 11/29/2004 onward use the 4157, reflecting a mid-year assembly change.
The 2005 Navigator liftgate tail light specifies the 916 bulb, whereas the 2004 liftgate specifies the 3157. These are fundamentally different bulb types, with the 916 being a single-filament T15 and the 3157 being a dual-filament T25, confirming that liftgate assemblies changed between those two model years.
The upper tail light position on the Lincoln Navigator (2003-2006) uses the 916 bulb, while the same position on 2007-2014 models uses the 906. The shift from an 18W T15 to an 8W T10 suggests a redesign of the upper tail light assembly between the second and third generation of the Navigator.
All bulb types listed across both tail light positions conform to ANSI standards applicable in both the United States and Canada, indicating consistent specification requirements across North American market vehicles.
The lower tail light on Lincoln Navigator models from 1998-2004 and again from 2011-2014 specifies the 3157, making it the most frequently recurring bulb type across the full production span covered in these specifications.
