Additional Notes

The Ford E-150 back up light specifications span model years 1975 through 2014, with three distinct bulb types appearing across that range: 1156, 2356, 2456, and 3156.
The 1156 bulb is a single-filament type with a BA15s bayonet base, rated at 12V and 21W under the ANSI standard applicable in both the US and Canada. It is the specified back up light bulb for the Ford E-150 from 1975 through 1991.
The 3156 is a single-filament wedge bulb in the T25 form factor, rated at 12V and 27W, also conforming to ANSI standards. It is specified for the Ford E-150 in 1992, 1993, 1995, 2000, 2002, 2003, 2010, and 2011.
The 2356 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V and conforming to ANSI standards. It is specified for the Ford E-150 in 1997-1998, 2006-2008, and 2013, as well as 1994 and 2001.
The 2456 is a festoon-style bulb designated for specialty applications, rated at 12V and conforming to ANSI standards. It is specified for the Ford E-150 in 1996, 1999, 2004-2005, 2009, and 2012, as well as 2014.
The 1156 and 3156 both use single-filament configurations, but they differ in base type. The 1156 uses a BA15s bayonet base while the 3156 uses a wedge base, making the two types physically non-interchangeable despite their shared single-filament design.
The 2356 uses a BAY15d bayonet base, which is a dual-contact base designed to accommodate two filaments. This base type is physically distinct from the BA15s base of the 1156, and the two are not interchangeable.
The 2456 festoon bulb uses a cylindrical form factor with end-cap contacts rather than a bayonet or wedge base. This construction is incompatible with sockets designed for the 1156, 2356, or 3156 bulbs.
Because the Ford E-150 back up light socket type varies by model year, the correct bulb size for a specific year must be confirmed before replacement, as physically incompatible types are present across the production range.
All four bulb types in these specifications conform to ANSI standards recognized in both the United States and Canada, indicating consistent regulatory compliance across the full model year range covered.
