For most 2017 Focus models sold in North America, the standard halogen setup uses H11 for the low beams and 9005 for the high beams, with H11 commonly used for the fog lights as well. If your car has HID or LED headlights, or if you’re in a different region, the bulb types may differ. Always verify with your owner's manual or by inspecting the bulb in place.
Automakers vary by trim and market, so the exact bulb type isn’t universal for every 2017 Focus. This article explains the typical configurations and provides steps to confirm the correct bulb for your particular vehicle.
Common bulb configurations for the 2017 Ford Focus
These are the bulb types most commonly found on 2017 Focus models with standard halogen headlights. Use this as a starting point, but confirm with the exact variant of your car.
- Low beam: H11 halogen
- High beam: 9005 (HB3) halogen
- Fog lights: typically H11 halogen (some regional variants may use different types)
- Note: If your Focus uses xenon HID or LED headlamps, the replacement bulbs are not H11/9005; refer to the manual or Ford parts catalog for the correct part number.
These configurations cover the most common halogen-equipped trims, but several markets offered different options over the model's lifecycle. Always check the actual bulb installed in your headlight or your vehicle’s documentation.
How to confirm the exact bulb for your car
Before you buy, confirm the specific bulb type using one of the following methods. A quick check can prevent buying the wrong part.
- Inspect the bulb in the headlight housing by removing the dust cover and the bulb to read the marking on the base (e.g., H11, 9005).
- Consult your owner’s manual or the official Ford parts catalog by entering your vehicle’s VIN or model year and trim.
- Bring the old bulb or a photo to an auto parts store or use an online part finder to match the exact bulb type.
- Note any trims with HID/LED headlights, which require a completely different replacement approach (ballasts and modules for HID, or integrated LED assemblies).
Conclusion: The quickest way to ensure a perfect fit is to verify the exact bulb type shown on the bulb itself or in the vehicle documentation, as there are regional and trim-based variations.
Summary
In brief, for a 2017 Ford Focus with standard halogen headlights in many markets, expect H11 for low beams, 9005 for high beams, and likely H11 for fog lights. If your model has HID or LED headlights, consult the owner’s manual or Ford’s parts catalog for the correct replacement. Always verify before purchasing to account for trim- and region-specific differences.
