Typically, the low-beam headlight bulbs on a 2011 Hyundai Sonata are H11 and the high-beam bulbs are 9005. Fog lights, if your trim includes them, usually use H11 as well. Some higher-trim Sonatas with factory HID headlights use xenon bulbs (D1S or D2S) instead of halogen bulbs. Always verify the exact bulb type for your vehicle by checking the owner's manual or the bulb label on the headlamp housing.
Halogen headlights: standard configuration
For most 2011 Sonatas with halogen headlights, the following bulb types are used in the primary headlamp assemblies.
- Low-beam bulb: H11
- High-beam bulb: 9005 (HB5)
- Fog lights (if equipped): H11
Note: Trim differences or aftermarket replacements can affect exact bulb types. Always confirm with the manual or by inspecting the installed bulb.
Factory HID headlights (optional on some trims)
Some higher-trim models or packages offer factory HID headlights, which use xenon bulbs rather than halogen bulbs. The exact bulb type depends on the headlamp assembly, but common HID bulbs are D1S or D2S.
- Low-beam HID bulb: D1S or D2S (assembly dependent)
- High-beam: typically integrated within the HID system or not a separate bulb; consult your manual for the specific configuration
Because HID configurations can vary by market and trim, verify the precise bulb type for your vehicle through the owner's manual or Hyundai dealer resources.
How to confirm the exact bulb on your car
Use these steps to ensure you buy the correct bulbs for your specific car configuration.
- Check the owner's manual section on bulb replacement for the exact specification by trim and year.
- Inspect the bulb currently installed by removing the headlight housing cover and reading the markings on the bulb itself (e.g., H11, 9005, D1S, D2S).
- Look for a label on the headlight housing or within the engine bay that lists the recommended bulb type for your model year.
- If in doubt, contact a Hyundai dealer or reference the vehicle identification number (VIN) with a parts specialist for an exact match.
These checks help ensure you purchase the correct bulb and avoid mismatches due to trim-level differences or aftermarket replacements.
Summary
In short, the typical halogen configuration for a 2011 Hyundai Sonata uses H11 for low beams, 9005 for high beams, and H11 for fog lights if equipped. Some higher trims with factory HID headlights use HID bulbs (D1S or D2S) rather than halogen bulbs. Always confirm with the owner's manual or by inspecting the current bulb markings to ensure you have the correct replacement for your specific vehicle.
