Ford Escape Parking Light Bulb Size

Additional Notes

• The Ford Escape front parking light draws from two distinct wedge bulb families across its model years: the T20 form factor, used in 2018-2023 models, and the larger T25 form factor, used in 2001-2012 models. Both families operate on a 12V system.
• The 7440NA is a single-filament T20 wedge bulb rated at 21W and is specified for the Ford Escape (2021-2023) front parking light position. Its natural amber glass produces the amber color output without relying on a tinted housing or colored lens coating.
• The 7444NA is a dual-filament T20 wedge bulb rated at 21W and 5W, specified for the Ford Escape (2018-2020) equipped with projector headlamps. The dual-filament design allows the same bulb to serve two brightness levels within a single socket.
• For 2018-2019 models without projector headlamps, the Ford Escape front parking light uses the 7443 instead of the 7444NA. The 7443 shares the same T20 form factor and 21W/5W dual-filament rating but lacks the natural amber glass of the 7444NA.
• The headlamp configuration on 2018-2019 Ford Escape models directly determines which T20 bulb is required. Substituting the 7443 for the 7444NA, or vice versa, would result in a color output mismatch in vehicles where the housing does not provide its own amber filtering.
• The 7440NA and 7444NA share the same T20 wedge base and voltage rating, but differ in filament count. The 7440NA is single-filament while the 7444NA is dual-filament, making them non-interchangeable despite their physical similarity.
• The 3357NA is a single-filament T25 wedge bulb rated at 27W with natural amber glass, specified for the 2010-2012 model years. At 27W, it operates at a higher wattage than the T20 bulbs used in later Escape generations.
• The 3457NA and 3157NA are both dual-filament T25 wedge bulbs rated at 27W/7W with natural amber glass. The 3457NA is specified for 2008-2009 models, while the 3157NA covers the 2001-2007 range.
• Although the 3457NA and 3157NA share identical wattage ratings and the same T25 wedge form factor, they carry different ANSI designations, which reflects differences in their internal filament geometry and pin configuration that affect socket compatibility.
• All bulb types listed across the Ford Escape front parking light specifications carry the NA suffix or are otherwise noted as natural amber, indicating that amber color compliance for parking light regulations is achieved through the glass envelope rather than through an external lens on these applications.
