Ford Taurus X high beam headlight bulbs use 9005 size while low beam headlight bulbs use H11 size. The replacement chart covers 2008 to 2009 vehicle production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford Taurus X uses two distinct halogen bulb types across its headlight system: the 9005 for high beam and the H11 for low beam, both operating on a 12-volt electrical system for the 2008-2009 model years.
The 9005 bulb follows the ANSI standard, which governs bulb specifications in the United States and Canada. It draws 65 watts and uses a P20d base, a single-contact bayonet-style fitting.
The H11 bulb follows the ECE standard, an internationally recognized regulatory framework originating in Europe. It draws 55 watts and uses a PGJ19-2 base, a keyed plug-in connector designed to prevent incorrect orientation during installation.
Both the 9005 and H11 are single-filament halogen bulbs, meaning each serves only one lighting function. This contrasts with dual-filament bulbs, which handle two functions within a single housing.
The H11 carries approval for use in the United States despite its ECE origins, reflecting its acceptance across multiple regulatory frameworks.
The 9005 and H11 use physically different base types, the P20d and PGJ19-2 respectively, making the two bulbs non-interchangeable with each other within the Taurus X headlight assembly.
