The Lincoln LS tail light utilizes bulb sizes 2458 and 3157 for the rear lighting components. Available information covers the period from 2000 through 2006 for the specified vehicle.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Lincoln LS outer tail light uses the 3157 bulb across all model years covered in the specifications, spanning 2000-2006.
The 3157 is a dual-filament wedge bulb of the T25 type, rated at 12V with a wattage of 27W on the high filament and 7W on the low filament, conforming to ANSI standards for the US and Canada.
The dual-filament design of the 3157 allows a single bulb to serve two lighting functions within one housing, which is typical for tail light assemblies that combine stop and running light duties.
The Lincoln LS inner tail light uses the 161 bulb for the 2000-2002 model years.
The 161 is a miniature wedge bulb of the T10 type, rated at 12V and 1W, also conforming to ANSI standards for the US and Canada.
The 161 and 3157 are both wedge-base bulbs, but they are not interchangeable. The T10 and T25 designations indicate different physical sizes, and their wattage ratings differ substantially, making substitution between the two unsuitable for any position.
The 3157 bulb appears in both the inner and outer tail light positions across different year groupings, but the inner tail light position for 2000-2002 is specifically assigned the 161, not the 3157.
