Additional Notes

The 3157 bulb is the most frequently specified brake bulb across Ford Ranger model years, covering 1991-1999, 2000-2004, and the 2023 model year with Type 1 lamp fitment. It is a dual-filament T25 wedge bulb rated at 12V with a 27W high-filament and 7W low-filament output, conforming to ANSI standards for the US and Canada markets.
The 7443 bulb is specified for the Ford Ranger brake light position across the 2019-2022 model years. It is a dual-filament T20 wedge bulb rated at 12V, 21W/5W, and is physically smaller than the T25 form factor used in earlier Ranger generations.
The 4157 bulb is specified for the 2008-2011 Ranger brake light position. Like the 3157, it is a dual-filament T25 wedge bulb rated at 12V, 27W/7W, though the two bulbs are not identical and interchangeability should not be assumed without verification.
The 1157 bulb differs from the wedge-type bulbs used in later Ranger model years. Specified for the 1983-1990 Ranger, it uses a BAY15d bayonet base rather than a wedge base, making it physically incompatible with sockets designed for T25 or T20 wedge bulbs.
The 2023 Ford Ranger brake bulb specification includes a Type 1 lamp condition, indicating that the 3157 fitment applies only to a specific lamp configuration. Vehicles with a different lamp type may require a separate bulb specification not reflected in this entry.
The 1996 Ranger is the only model year in the brake light position to use the 3156, a single-filament T25 wedge bulb rated at 12V, 27W. All surrounding model years use dual-filament bulbs, and the 3156 is not a drop-in substitute for the 3157 in applications requiring dual-filament function.
For the center high mount stop light position, the 912 bulb is the most commonly specified type, covering the 1993, 1998-2004, and 2019-2023 Ranger model years. It is a T15 wedge bulb rated at 12V, 12W, and is classified as a variant of the 921 bulb.
The 922 bulb is specified for the center high mount stop light on the 1994, 1996, and 2008-2011 Ranger. It shares the T15 wedge form factor with the 912 but operates at a higher wattage of 16W, meaning the two bulbs are not electrically equivalent despite their physical similarity.
The 906 bulb is specified for the center high mount stop light on the 1995 and 1997 Ranger. It is a T10 miniature wedge bulb rated at 12V, 8W, which is a smaller and lower-wattage unit than either the 912 or 922, and it is not interchangeable with T15 wedge sockets.
All bulb types listed across both the brake light and center high mount stop light positions conform to ANSI standards applicable to the US and Canada markets, indicating standardized electrical and mechanical specifications within those regions.
