Short answer: The 2011 Corolla generally uses standard halogen bulbs—low beams are H11 and high beams are 9005 (HB3). If your car has fog lights, those are typically H11 as well.
The exact bulb configuration can vary by trim level and market. This article outlines the common North American setup and provides guidance on how to verify the correct bulbs for your specific vehicle.
Headlight bulb types by function
Below is a quick reference for the primary bulb types you’re likely to encounter in a 2011 Corolla headlight system.
- Low beam (headlights): H11 halogen bulb
- High beam (headlights): 9005 bulb (HB3) halogen
- Fog light (if equipped): H11 halogen bulb
Note that some trims or regional variations might use slightly different bulbs or even HID projectors. When in doubt, verify with your vehicle’s manual, inspect the existing bulb markings, or check the headlight housing for a bulb type label.
Trim and market variations
North American market
In many North American 2011 Corolla models, the standard configuration uses H11 for low-beam headlamps, 9005 for high-beam headlamps, and H11 for any factory-installed fog lights. Some trims or packages may alter this setup or provide different lighting options, such as fog lights without changing the main headlamp bulbs.
Other markets
Markets outside the United States and Canada sometimes differ in bulb suppliers or naming conventions. While H11 and 9005 are common, a few regions may use alternative halogen bulbs or headlights with different module designs. Always check the owner’s manual or inspect the bulb itself to confirm the exact type for your car.
Special cases: HID and LEDs
Some 2011 Corollas marketed in certain regions offered HID (xenon) headlights as an option or within specific trims. If your vehicle has HID headlights, you will typically see a D3S or D2S/HID-type bulb rather than a standard H11 or 9005, and the housing may be projector-style with different ballast requirements. LED headlights are not standard on the 2011 Corolla and are uncommon as factory equipment on most 2011 models; aftermarket conversions would require additional components.
Summary
For the 2011 Toyota Corolla, the typical headlight setup uses halogen bulbs: low beams H11, high beams 9005, and fog lights (if equipped) H11. Trim and market variations can alter these choices, and a small number of cars may have HID options. Always confirm with the owner’s manual or by inspecting the current bulbs to ensure you buy the correct replacements.
