The headlights on a 2009 Toyota Tacoma typically use two separate halogen bulbs: low beam H11 and high beam 9005. Fog lights (if equipped) usually use H3. Some regional or trim variations exist, so verify on your vehicle.
Standard headlight configuration
Most US-spec 2009 Tacomas follow a two-bulb setup for the main headlights, with distinct bulbs for low and high beams.
- Low beam: H11
- High beam: 9005
In typical configurations, these are the bulbs you'll replace when performing standard headlight maintenance.
Fog lights and possible variations
If your Tacoma is equipped with factory fog lights, those bulbs are typically a separate type from the main headlight bulbs.
- Fog lights: H3
Variations exist by trim level and international markets, including the possibility of different daytime running light setups or optional HID headlights. Always confirm by inspecting the bulb in place or consulting the owner's manual.
How to verify your exact bulb sizes
To ensure you purchase the correct replacements for your specific vehicle, use these verification methods.
- Check the bulb itself for a size or part number stamped on the base.
- Consult the owner's manual or service manual for the exact bulb specification.
- Inspect the headlight socket or ballast (if HID) to identify compatible bulb types.
- Ask a Toyota dealer or a trusted mechanic if you’re unsure.
Verifying on the vehicle prevents fitment issues and ensures optimal brightness and beam pattern.
Summary
For a typical 2009 Toyota Tacoma with halogen headlights, the standard configuration is low beam H11 and high beam 9005, with H3 used for fog lights if the vehicle is equipped with them. Expect possible variations by trim or international markets, so always confirm against your specific vehicle before purchasing replacements. Ensuring you have the correct bulbs helps maintain proper illumination and safety on the road.
Do I need H11 or 9005?
H11 bulbs are designed for use as low beam headlights, while 9005 bulbs are typically used for high beams. This results in a higher brightness level for the 9005 bulbs compared to the H11 bulbs.
