Toyota 4Runner Fog Light Bulb Size

Additional Notes

• The Toyota 4Runner front fog light specifications cover model years 1998-2024 and reference four distinct bulb types: H11, H16, 9006, and H3.
• The H11 and H16 bulbs follow the ECE standard used in Europe and worldwide, while the 9006 bulb follows the ANSI standard used in the US and Canada. The H3 bulb holds ECE certification and is also approved in the US and Japan.
• All four bulb types are single-filament halogen designs, meaning each bulb controls only one lighting function rather than combining two in a single unit.
• The H11 (PGJ19-2 base) and H16 (PGJ19-3 base) share a similar base family but are not interchangeable. Their base suffixes indicate different pin configurations, and swapping one for the other is not supported by the specifications.
• The 4Runner (2021-2024) uses the H11 bulb, which operates at 12V and 55W.
• Model years 2010-2020 use the H16 bulb, which also operates at 12V but draws only 19W, making it a notably lower-wattage unit than the other three bulb types listed.
• The 9006 bulb, used on the 2003-2009 model years, operates at 12V and 55W and uses a P22d base. It is not cross-compatible with the ECE-standard bulbs listed in these specifications.
• The H3 bulb, used on the 1998-2002 model years, operates at 12V and 55W and uses a PK22s base, which is a single-pin axial design distinct from the bases found on the H11, H16, and 9006 bulbs.
• The 1998 model year entry specifies a halogen H3 bulb produced from July 1998 onward, indicating a mid-year production change for that model year.
• Because the H11, H16, 9006, and H3 bulbs each use a different base type, none of the four are physically interchangeable with one another without modification.
