The low-beam bulb is typically H11, the high-beam bulb is 9005, and the fog lights (if equipped) use H11 as well.
In practice, bulb types can vary by trim level and market. Some regions or specific trims may use different bulbs for certain functions. Always verify by checking the current bulb, consulting the owner's manual, or referring to the vehicle’s bulb label under the hood.
Bulb types by function
Before listing the common bulb codes, it helps to know which bulb goes where so you can prepare replacements accurately.
- Low beam: H11
- High beam: 9005 (also labeled HB3 on some bulbs)
- Fog lights (if equipped): H11
Note: Some markets or trims may use different bulbs for fogs or low beams (for example, H16 or other variants). If in doubt, read the markings on the bulb you remove or consult the owner's manual for your exact configuration.
Replacement tips
When replacing bulbs, ensure the ignition is off, the headlights are cool, and you handle bulbs with clean gloves or a cloth to avoid oil on the glass. Locate the access points in the engine bay or wheel well as appropriate for your trim, twist to remove the old bulb, and align the new bulb securely before testing.
Additional considerations
If your 2012 Honda Fit is part of a non-U.S. market or a different trim level, bulb specifications may differ. If you’ve replaced a bulb and it doesn’t fit or function correctly, double-check the exact bulb code in your manual or by inspecting the current bulb before purchasing replacements.
Summary
For the 2012 Honda Fit, the typical setup is H11 for low beams, 9005 for high beams, and H11 for fog lights when present. Variations by trim and region are possible, so always confirm with the manual or by inspecting the existing bulb before buying replacements.
