Ford Maverick Brake Bulb Size

Ford Maverick brake bulbs utilize WT21/7W and 1157 sizes, while the center high mount stop light requires a 912 bulb size. The replacement chart covers vehicle production spanning 1970 to 2026 with corresponding bulb size specifications.

Additional Notes

The Ford Maverick uses two distinct brake bulb types across its production history: the WT21/7W for the 2022-2026 model years and the 1157 for the 1970-1977 model years.
The WT21/7W is a Ford OEM part rather than an ANSI-standardized bulb, which distinguishes it from the other bulb types present in these specifications.
Both the WT21/7W and the 1157 are dual-filament bulbs, meaning each serves two lighting functions from a single unit, typically combining stop and tail light operation.
The WT21/7W uses a T20 wedge base and operates at 12V with a 21W/7W dual-filament rating, while the 1157 uses a BAY15d bayonet base at 12V with a 21W/5W rating, making the two bulbs physically and electrically incompatible with each other.
The WT21/7W was originally introduced in 2021-era Ford platforms including the F-150, Bronco, and Maverick, placing the Maverick within a shared Ford OEM bulb family for its brake lighting.
The 1157 conforms to ANSI standards applicable in both the US and Canada, a classification that reflects its broad cross-vehicle compatibility within the North American market.
The Ford Maverick (2022-2026) uses a 912 bulb for the Center High Mount Stop Light, a separate specification from the main brake bulb used on the same model years.
The 912 is a T15 wedge bulb operating at 12V and 12W, and it is a variant of the 921 bulb, indicating a close but not identical relationship between the two part numbers.
Unlike the dual-filament WT21/7W and 1157 brake bulbs, the 912 used in the Center High Mount Stop Light is a single-function bulb, consistent with the dedicated stop-only role of that lamp position.
The BAY15d bayonet base of the 1157 requires a twist-lock socket, while the wedge bases of the WT21/7W and 912 use friction-fit sockets, meaning the socket type in the vehicle housing determines which bulb format is physically compatible.
