The Ford E-250 brake light specifications cover model years 1975 through 2014, with three distinct bulb types used across that span: the 1157, 3157, and 3357.
The 3357 is a single-filament wedge bulb in the T25 form factor, rated at 12V and 27W under the ANSI standard applicable in the US and Canada. Because it carries only one filament, it serves a dedicated brake or turn signal function rather than a combined stop/tail role.
The 3157 shares the same T25 wedge form factor and 12V rating as the 3357 but is a dual-filament type, operating at 27W on the high-intensity filament and 7W on the low-intensity filament. This dual-filament design allows a single bulb to handle both the brake signal and a continuous tail-light function.
The 1157 is also a dual-filament bulb, rated at 12V with filaments at 21W and 5W, but it uses a BAY15d bayonet base rather than a wedge base. This base type is physically incompatible with the T25 wedge sockets used by the 3157 and 3357, making cross-substitution between the 1157 and the other two types impossible without a socket adapter.
The Ford E-250 used the 1157 for brake lighting from 1975 through 1991, representing the longest continuous run of a single bulb type in these specifications.
The 3357 replaced the 1157 for model years 1992-1995, marking a shift from a bayonet-base dual-filament bulb to a single-filament wedge type for the brake light position.
The 3157 was specified for the Ford E-250 from 1996 through 2003. Although the 3157 and 3357 share the same T25 wedge base and physical housing, their filament configurations differ, and substituting one for the other would alter the electrical behavior of the brake light circuit.
The 3357 returned as the specified brake bulb from 2004 through 2014, the final model year in these specifications.
The center high mount stop light on the Ford E-250 used the 912 bulb for every model year listed, spanning 1992 through 2014. The 912 is a T15 wedge bulb rated at 12V and 12W, and it is a variant of the 921 bulb within the same wedge family.
The 912 and 921 share a wedge base and are close variants, though their wattage ratings differ slightly. The 912 is rated at 12W while the 921 is typically rated at 18W, so the two are not always interchangeable without confirming socket and circuit compatibility.
