Ford E-150 brake bulb sizes include 3357, 3157, and 1157, with the center high mount stop light using a 912 bulb size across multiple generations. The replacement chart covers vehicle production spanning 1975 to 2014.

The Ford E-150 brake bulb specifications span model years 1975 through 2014, with three distinct bulb types used across that range: the 1157, 3157, and 3357.
The 3357 is the most frequently specified brake bulb across the E-150 range, covering model years 1992-1995 and 2004-2014. It is a single-filament wedge bulb in the T25 form factor, rated at 12V and 27W, and conforms to the ANSI standard used in the US and Canada.
The 1157 is the second most common bulb in these specifications, used across model years 1975-1991. It operates on a dual-filament design with a BAY15d bayonet base, rated at 12V with filaments drawing 21W and 5W respectively.
The 3157 is specified for model years 1996-2003. Like the 3357, it is a T25 wedge bulb rated at 12V, but it carries a dual-filament design with power ratings of 27W and 7W, distinguishing it functionally from the single-filament 3357.
Although the 3357 and 3157 share the same T25 wedge form factor and a 27W primary filament rating, the 3157 includes a secondary 7W filament while the 3357 does not. This difference makes them non-interchangeable in applications that rely on dual-filament operation.
The 1157 uses a BAY15d bayonet base, which is physically incompatible with the wedge-style socket used by the 3357 and 3157. Substitution between the 1157 and either wedge-type bulb is not possible without a socket adapter.
The Center High Mount Stop Light on the Ford E-150 uses the 912 bulb exclusively across all specified model years, 1992-2014. The 912 is a T15 wedge bulb rated at 12V and 12W, and it is classified as a variant of the 921 bulb type.
The 912 and 921 share the same T15 wedge base, though they differ in wattage. The 912 is rated at 12W while the 921 is typically rated at 18W. This wattage difference is relevant when considering one as a substitute for the other in a given socket.
All four bulb types in these specifications conform to ANSI standards applicable in the US and Canada, indicating standardized electrical and physical tolerances across the range.
The brake light circuit on the E-150 transitioned from a bayonet-base dual-filament design to wedge-base configurations beginning with the 1992 model year, with the specific wedge type varying between the 3357 and 3157 at different points in the vehicle's production history.
