The Ford Transit Connect brake light utilizes a 7443 bulb size for illumination across all listed vehicle versions. Data provided covers a span of time starting from 2010 through 2023.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford Transit Connect uses the 7443 bulb for brake lighting across the 2010-2023 model years, making it the sole bulb type specified for that function throughout the entire production range covered by these specifications.
The 7443 is a dual-filament wedge bulb classified under the T20 form factor, operating at 12 volts with a wattage rating of 21W on the high-filament circuit and 5W on the low-filament circuit. The dual-filament design allows a single bulb to serve both brake and tail light functions within one housing.
The 7443 carries ANSI standardization for the US and Canadian markets, meaning its physical and electrical specifications conform to a defined industry standard rather than a proprietary format.
The center high mount stop light on the Ford Transit Connect for the 2019-2020 model years uses the 921 bulb, which is a separate specification from the main brake bulb used on the same vehicles.
The 921 is a single-filament wedge bulb classified under the T15 form factor, operating at 12 volts with a rating of 16W. Its single-filament construction reflects its dedicated stop-light-only role in the center high mount position.
The T15 form factor of the 921 and the T20 form factor of the 7443 are physically distinct wedge base sizes. These two bulbs are not interchangeable despite both using wedge-style bases, as the socket sizes and wattage ratings differ between the two classifications.
The 921 also carries ANSI standardization for the US and Canadian markets, consistent with the 7443 in terms of regional specification compliance.
