For most 2016 Focus models with halogen headlights, the front low beams use H11 bulbs, the high beams use 9005 bulbs, and the fog lights (if equipped) use H11. If your car has factory HID headlights, the primary bulbs are D3S. Always verify with the owner’s manual or by inspecting the current bulb to confirm the correct type.
Halogen headlight configuration
The following list covers the typical bulb designations for a 2016 Focus equipped with standard halogen headlights.
- Low beam (dipped beam): H11
- High beam: 9005 (HB3)
- Fog lights (where equipped): H11
Note: Some trims may use different fog light bulbs or have DRL arrangements that differ from the basic halogen setup. If your fog lights aren’t H11, check the bulb itself or the owner's manual for the exact specification.
HID headlight option
Some 2016 Focus models were equipped with factory HID headlights. In those cases, the main headlamp bulb is an HID bulb, commonly a D3S type. The high-beam configuration can vary by trim, with some setups using a separate halogen high beam (often 9005) and others using HID for both beams. Verify your specific vehicle’s configuration against the manual or Ford’s parts diagrams.
- Low beam: D3S (typical HID installation)
- High beam: Usually a separate bulb (often 9005) or HID depending on the exact setup
To confirm the exact bulbs for your car, check the existing bulb, VIN-specific documentation, or Ford’s official diagrams for your trim level.
How to identify your bulb type
Use these steps to verify the correct bulb type on your specific vehicle without guessing:
- Open the hood and locate the headlight assembly behind the clear lens near the wheel well.
- Carefully release the bulb socket or access cover and pull out the bulb by the base portion, not the glass.
- Check the markings on the bulb base or consult the owner's manual to read the exact bulb code.
- If unsure, bring the old bulb to an auto parts store or consult Ford’s parts diagrams for your VIN.
Knowing the exact bulb code helps you avoid incorrect replacements and ensures the correct fit and beam pattern.
Replacement tips and cautions
Follow these best practices when replacing headlight bulbs on a 2016 Focus to ensure safety and proper operation:
- Wear gloves or use a clean cloth to prevent oil from your skin transferring to halogen bulbs, which can shorten bulb life.
- Disconnect the negative battery terminal if you’re working near electrical connections to prevent short circuits.
- Make sure the headlight switch is off and the assembly is cool before handling the bulbs.
- When one bulb fails, consider replacing the pair to maintain even brightness and color temperature.
If you’re unsure about bulb type or the replacement process, consult a professional technician or a Ford dealer to avoid damage to the headlight assembly or electrical system.
Summary: For 2016 Ford Focus models with halogen headlights, use H11 for low beam, 9005 for high beam, and H11 for fog lights (if equipped). If the car has HID headlights, the main bulbs are typically D3S, with high-beam configurations varying by trim. Always verify with the owner’s manual or VIN-specific diagrams to ensure you select the correct bulbs.
