Ford EcoSport front turn signal bulbs utilize 7440NA, 7443, or 7444NA size specifications, while rear turn signal bulbs require the 7440NA bulb size. The replacement chart covers 2018 through 2021 vehicle production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford EcoSport rear turn signal position uses the 7440NA bulb across all four model years covered in the specifications, from 2018-2021.
The 7440NA is a single-filament T20 wedge bulb rated at 12V and 21W, with natural amber glass that produces an amber output without the need for an amber-tinted lens or housing.
The front turn signal position on the Ford EcoSport does not share a consistent bulb type across model years, with three different bulb sizes specified depending on the year.
The 7444NA, used in the 2018-2019 front turn signal position, is a dual-filament T20 wedge bulb rated at 12V with a 21W main filament and a 5W secondary filament, and it also features natural amber glass.
The 2020 front turn signal uses the 7443, which is a dual-filament T20 wedge bulb rated at 12V, 21W/5W, but unlike the 7444NA it has clear glass rather than natural amber glass.
The 2021 front turn signal reverts to the 7440NA, a single-filament bulb, which differs functionally from the dual-filament 7444NA used in 2018-2019 despite both carrying natural amber glass.
The dual-filament design of the 7443 and 7444NA allows a single bulb to serve two lighting functions simultaneously, such as a turn signal and a parking light, while the single-filament 7440NA serves only one function.
All three bulb types in these specifications conform to ANSI standards applicable in the US and Canada, and all share the T20 wedge base form factor, though filament count and glass tint differ between them.
Because the 7440NA is single-filament and the 7444NA is dual-filament, the two are not directly interchangeable in positions that require both filaments to operate, despite sharing the same T20 wedge base and natural amber glass.
The 7443 and 7444NA share identical voltage and wattage ratings and the same T20 wedge base, with the sole distinction being that the 7444NA incorporates natural amber glass while the 7443 does not.
