Toyota Corolla Fog Light Bulb Size

Additional Notes

• The Toyota Corolla front fog light specifications cover model years 2000 through 2016, with four distinct bulb types used across that span: H3, 9006, H11, and H16.
• The H11 and 9006 bulbs share the same 12V, 55W electrical rating, as does the H3, yet all three use physically different bases, making them non-interchangeable despite identical wattage.
• The H16 is a single-filament halogen bulb operating at 12V and 19W with a PGJ19-3 base, governed by the ECE standard. Its lower wattage distinguishes it from all other bulb types listed in these specifications.
• The H11 uses a PGJ19-2 base and carries both ECE approval and US approval, making it one of the more broadly accepted standards among the bulb types present in these specifications.
• The 9006 bulb follows the ANSI standard applicable to the US and Canada, with a P22d base. It differs from the ECE-governed H11 in both base design and regulatory origin, despite sharing the same 12V, 55W rating.
• The Toyota Corolla (2014-2016) uses the H16 bulb for the front fog light, which operates at a notably lower wattage than the H11 used in the preceding 2009-2013 model years, indicating a change in the fog light circuit design between those generations.
• The 2000 model year carries a partial-year fitment note specifying the 9006 bulb applies from May 2000 onward, indicating that earlier production units of that model year may not share the same front fog light fitment.
• The H3 bulb, used on the Toyota Corolla from 2001 through 2004, features a PK22s base and holds ECE, US, and Japanese approval, giving it the widest multi-region regulatory acceptance of any bulb type in these specifications.
