This 2010 Ford Focus bulb size page is designed to help you verify the correct bulb by lighting position before you buy replacement parts. Because the Focus could be equipped differently depending on trim, body style, and market, checking the exact lamp location is the safest way to match the right bulb for your car.
Use the chart on this page to find common exterior and interior bulb sizes for the 2010 Ford Focus, including headlights, tail lights, brake lights, turn signals, license plate lights, and cabin lamps. Matching the bulb to the correct position helps avoid returns and makes replacement faster and easier.
Fitment can vary on the 2010 Ford Focus, especially between trim levels, factory lighting packages, halogen setups, and aftermarket upgrades. Some owners replace standard halogen bulbs with LED alternatives, but not every LED will fit or perform the same way in every housing. Before ordering, compare the installed bulb in your vehicle with the bulb size listed here, and if possible remove the old bulb to confirm the base and connector style. That extra check is especially useful for fog lights, headlight conversions, and any bulb that may have been changed previously by a past owner.
