Ford Focus high beam and low beam headlight bulbs utilize H1 and H11 sizes respectively, with 9008 designations available for replacement applications. The replacement chart covers vehicle production spanning 2008 to 2018, detailing bulb size specifications across this period.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford Focus uses three distinct halogen bulb types across its high beam and low beam headlight positions: H1, 9008, and H11.
The 9008 bulb follows the ANSI standard used in the US and Canada. It is a dual-filament halogen bulb with a P26t base, rated at 12V and 65W/55W, where the higher wattage serves the high beam filament and the lower serves the low beam.
On the 2008-2011 Ford Focus, the 9008 bulb serves both the high beam and low beam positions from a single dual-filament unit, a design that consolidates both functions into one socket.
The H1 bulb follows the ECE standard used in Europe and worldwide, though it also carries approval in the US and Japan. It is a single-filament halogen bulb with a P14.5s base, rated at 12V and 55W.
The H11 bulb also follows the ECE standard and carries US approval. It is a single-filament halogen bulb with a PGJ19-2 base, rated at 12V and 55W.
From 2012 onward, the Ford Focus separates the high beam and low beam into two distinct bulb types, with H1 handling the high beam position and H11 handling the low beam position.
The H1 and 9008 bulbs are not interchangeable. They use different base types, P14.5s and P26t respectively, and the 9008 carries two filaments while the H1 carries only one.
On the 2015-2018 Ford Focus Hatchback equipped with HID headlights, the high beam position uses an H13 bulb rather than the H1 found on the Sedan, making body style a critical factor in fitment for those model years.
The 2014 Ford Focus low beam specification notes compatibility specifically with halogen capsule headlamps, indicating that not all trim configurations for that year use the H11 bulb in the low beam position.
Because H1 and H11 are both single-filament ECE-standard bulbs rated at 12V and 55W, their electrical ratings are identical, yet their base types differ and they are not physically interchangeable with each other or with the 9008.
