Toyota Tacoma Fog Light Bulb Size

Additional Notes

• The Toyota Tacoma front fog light specifications reference three distinct bulb types across the 2005-2023 model years: H16, H11, and 9145. All three are single-filament halogen bulbs operating at 12 volts, though they differ in wattage and base type.
• The 9145 bulb follows the ANSI standard used in the United States and Canada. It carries a PY20d base and a 42-watt output, and it appears in the Toyota Tacoma front fog light position across the 2005-2011 model years.
• The H11 bulb follows the ECE standard recognized in Europe and worldwide, and it holds approval for use in the United States as well. It uses a PGJ19-2 base and operates at 55 watts, making it the highest-wattage bulb among the three types listed in these specifications.
• The H16 also follows the ECE standard and shares the same single-filament halogen construction as the H11, but it uses a PGJ19-3 base and operates at a notably lower 19 watts.
• Although the H16 and H11 are both ECE-standard halogen bulbs, their base types are different. The PGJ19-3 base of the H16 and the PGJ19-2 base of the H11 are not interchangeable, and substituting one for the other in the Toyota Tacoma is not supported by these specifications.
• The 9145 and H11 bulbs are similarly incompatible with each other. The 9145 uses a PY20d base under the ANSI standard, while the H11 uses a PGJ19-2 base under the ECE standard, and no cross-compatibility between these two types is indicated in the specifications.
• The 2022 Toyota Tacoma specifies an H11 bulb for the front fog light, while the 2021 and 2023 model years specify an H16. This means the 2022 model does not share a fog light bulb fitment with the immediately adjacent model years.
• The H11 is the most frequently listed bulb type in these specifications, covering the 2012-2015 model years as well as 2022, for a total of five model years across the dataset.
