The Ford Focus ST is a performance-focused hatchback, and bulb fitment can vary by model year, trim, and lighting package. This model page is here to help you narrow down the right year before you check the exact bulb sizes on the matching year page.
If you own a 2013, 2014, 2015, 2016, 2017, or 2018 Ford Focus ST, use this page as a starting point and then open the year-specific guide for exact bulb information. That is the best way to avoid ordering the wrong headlight, fog light, brake light, or interior bulb.
Because the Focus ST was sold across multiple years with possible changes in headlamp design, taillight setup, and optional equipment, the exact bulb size is not always the same from one year to the next. Some cars may also differ depending on factory lighting options or market-specific equipment. For that reason, the year page is the final reference for exact fitment, while this model page helps you choose the right path quickly and confidently.
FAQ
Why does the Ford Focus ST need a model page if bulb sizes are listed by year?
The model page gives you the big-picture fitment overview. It helps you confirm that you are looking at the correct Focus ST generation and then directs you to the exact year page, where the precise bulb sizes are listed.
Which years are covered on this Ford Focus ST model page?
This page covers the 2013 through 2018 Ford Focus ST model years. If your car is one of those years, you can use the matching year page to find the exact bulb fitment.
Can I use the same bulb sizes for every Ford Focus ST year?
Not always. Even within the same model line, bulb fitment can change from year to year. That is why bulbsize.org separates the model overview from the year-specific chart.
What should I check before ordering replacement bulbs for my Focus ST?
Check the model year, the specific lamp location, and whether your car has factory options such as halogen or HID/xenon lighting, if applicable. The year page will confirm the exact bulb size for each position.
Do trim level or lighting packages affect bulb fitment on the Focus ST?
Yes, they can. Some trims or packages may use different headlight or fog light setups, which can change the bulb type. Always match your car’s year and equipment before buying.
Where can I find the exact headlight bulb size for my Focus ST?
Use the year page for your specific Ford Focus ST model year. The model page is only a guide; the year chart gives the exact headlight bulb size and any related notes.
Are fog light bulbs the same across all Focus ST years?
They may not be. Fog light bulb fitment can vary depending on the year and lighting configuration. Check the year-specific page for the exact fog light bulb size before ordering.
What if my Focus ST has aftermarket headlights or taillights?
Aftermarket lighting can use different bulb types than the factory setup. In that case, the vehicle year alone may not be enough, so you should verify the lamp housing requirements or the manufacturer’s specifications.
How do I know if I should use the 2013 or 2014 Focus ST bulb chart?
Use the exact model year of your car, not the body style or trim name alone. A 2013 Focus ST should use the 2013 page, while a 2014 car should use the 2014 page.
Does this page include exact bulb part numbers?
No. This model page is meant to guide you to the correct year page. Exact bulb sizes and fitment details belong on the year-specific charts, where the information is more precise.
Can interior bulbs also vary by year on the Ford Focus ST?
Yes, interior bulb types can vary just like exterior bulbs. If you are replacing dome, map, trunk, or license plate bulbs, check the year page for the exact size used on your Focus ST.
What is the safest way to avoid buying the wrong bulb for my Focus ST?
Start with the model page, confirm your exact year, and then use the matching year chart for the final bulb size. That approach reduces guesswork and helps ensure the replacement fits correctly.
