Additional Notes

The Ford Escape front side marker uses three distinct bulb types across its model years: the 3157NA for 2001-2007, the 194 for 2008-2012, and the 168 for 2018-2020.
The 168 and 194 are both T10 miniature wedge bulbs operating at 12V, though they differ in wattage. The 168 draws 4.9W while the 194 draws 3.78W, making them physically similar but not electrically identical.
The 3157NA is a dual-filament T25 wedge bulb rated at 12V with a 27W high filament and 7W low filament. Its natural amber glass construction gives it a built-in color tint rather than relying on a colored lens.
The 4157 used in the rear side marker for 2008-2012 shares the same dual-filament T25 form factor and 27W/7W rating as the 3157NA, but lacks the natural amber glass coating.
The 2825 is a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. It is used in the Ford Escape rear side marker for 2021-2023.
The 168 and 2825 are both T10 wedge bulbs at 12V with close wattage values of 4.9W and 5W respectively, but the 2825 specifies a distinct W2.1x9.5d base, which affects physical fitment and interchangeability.
The 2020 Ford Escape front side marker uses the 168 bulb specifically with projector headlamps, indicating a trim-level or headlamp-type dependency for that model year.
The rear side marker on the Ford Escape shifted from the dual-filament 4157 used in 2008-2012 to the single-filament 168 for 2018-2020, representing a change in both filament count and bulb family.
