Ford Freestyle Back Up Light Bulb Size

The Ford Freestyle back up light requires bulb size 2356 or 2456 depending on the specific version of the component. Data for the bulb sizes covers the range from 2005 to 2007.

Additional Notes

The Ford Freestyle uses two distinct bulb types across its 2005-2007 model years for the back up light: the 2356 and the 2456, both governed by ANSI standards applicable in the US and Canada.
Both the 2356 and 2456 operate at 12 volts, which is consistent with standard automotive electrical systems.
The 2356 is a dual-filament bulb fitted with a BAY15d bayonet base, a base type that uses two offset pins to ensure correct orientation during installation.
The 2456 is a festoon-style bulb intended for specialty applications, a form factor that seats by compression between two end caps rather than using a bayonet or wedge base.
The 2356 bulb applies to the 2005 and 2007 Ford Freestyle, while the 2006 model year uses the 2456 instead.
Because the 2356 uses a BAY15d bayonet base and the 2456 uses a festoon mounting style, the two bulbs are physically incompatible and not interchangeable with each other.
The single-year use of the 2456 in the 2006 Ford Freestyle reflects a mid-generation fitment change, meaning parts sourced for adjacent model years would not be suitable for 2006 applications.
