For a 2011 Toyota Corolla with standard halogen headlights, the low beams typically use H11 bulbs and the high beams use 9005 (HB3). If your car is equipped with fog lights, those usually take H11 as well. Always confirm by checking the owner's manual or the existing bulb before buying replacements.
Standard bulb sizes for the factory halogen headlights
These are the common sizes used by the 2011 Corolla's headlight assemblies on most trims involving dual headlights and optional fog lights.
- Low beam: H11 (12V, about 55W)
- High beam: 9005 HB3 (12V, about 65W)
- Fog lights (if equipped): H11 (12V, about 55W)
Note: Some trims or aftermarket configurations may differ. Always verify by inspecting the bulb or consulting the owner's manual.
Notes on trim levels and upgrades
Not every 2011 Corolla model includes fog lights, and some owners upgrade to LED or HID kits. When upgrading, use bulbs that fit the socket and maintain the correct beam pattern. Aftermarket options may require CAN-bus adapters to prevent electrical issues or dashboard warning lights.
What to check before purchasing replacements
To avoid buying the wrong bulb, check one of these quick sources: the marking on the bulb itself, the owner's manual, or the vehicle’s information sticker inside the door jamb that lists bulb types. If in doubt, bring the old bulb to an auto parts store for direct comparison.
Summary
The 2011 Toyota Corolla’s standard halogen headlights use H11 for low beams, 9005 for high beams, and H11 for fog lights when equipped. Verify the exact requirement for your trim and consult the owner's manual or the existing bulb before purchasing replacements to ensure proper fit and safe operation.
