For most 2015 Toyota Tacomas with standard halogen headlights, the low-beam bulb is H11 and the high-beam bulb is 9005. Always verify by checking the owner's manual or the bulb label on the headlight assembly, since trim levels or optional packages can change bulb sizes.
In this article, we explain the typical bulb sizes, how to identify your exact configuration, and what to consider if your truck has upgrade headlights. While many Tacomas from this year use halogen bulbs, some trims or aftermarket options may differ, so always confirm before purchasing replacements.
Headlight bulb sizes by configuration
Below is the typical sizing for the common 2015 Tacoma headlight configurations. If your vehicle differs due to trim or aftermarket upgrades, consult the manual or a professional.
- Low-beam bulb: H11
- High-beam bulb: 9005 (HB3)
When replacing bulbs, consider changing both sides at the same time to maintain even lighting and color. Also ensure you select the correct wattage and type (halogen vs. LED) for your housing.
Other headlight configurations and considerations
On rare occasions, some higher-trim Tacomas may feature projector headlights or factory HID options. In those cases, the bulb type differs from standard halogen replacements, and you typically cannot substitute a halogen bulb without affecting performance. If your vehicle has HID or projector headlights, refer to the owner’s manual or confirm with a dealer or mechanic before purchasing bulbs.
How to identify the correct bulb on your Tacoma
Use these steps to confirm the exact bulb size for your specific truck:
- Check the owner’s manual or the information label inside the fuel door or headlight housing for bulb specifications.
- Inspect the back of the headlight housing for the bulb type imprint (for example, H11, 9005, or other codes).
- Carefully remove the old bulb to read the markings on the base, if safe to do so.
- Match the bulb part number or size to a reputable retailer or the Toyota parts catalog.
Tip: Always wear gloves or use a clean cloth when handling bulbs to avoid oils from your skin degrading the bulb’s performance and longevity.
Summary
For the 2015 Toyota Tacoma, the standard halogen setup typically uses H11 for low beams and 9005 for high beams. Always verify with the owner’s manual or the bulb label on your headlight housing, as trims and optional upgrades can vary. If your truck features projector headlights or an HID option, bulbs differ and may require different replacements or ballast components. When in doubt, consult a professional to ensure proper fitment and safe operation.
