Toyota Sequoia Fog Light Bulb Size

Additional Notes

• The Toyota Sequoia front fog light position uses two distinct bulb types across its model range: the 9145 for the 2008-2018 model years and the 9006 for the 2001-2007 model years.
• Both the 9145 and 9006 are ANSI-standardized halogen bulbs rated for 12-volt electrical systems, making them compatible with the standard automotive electrical architecture used across these vehicles.
• The 9145 is a single-filament halogen bulb rated at 42 watts and fitted with a PY20d base, which is a bayonet-style connector with a specific keying configuration.
• The 9006 is also a single-filament halogen bulb but draws 55 watts and uses a P22d base, a different bayonet connector type that is physically incompatible with the PY20d socket.
• Because the 9145 and 9006 use different base types, the two bulbs are not interchangeable despite both being single-filament 12-volt halogens. Installing the wrong type risks a fitment failure at the socket.
• The 13-watt difference between the 9006 (55W) and the 9145 (42W) reflects a meaningful gap in power draw, which is relevant when selecting aftermarket or replacement equivalents that must match the original wattage rating.
• Both bulb types carry ANSI standardization applicable to the US and Canadian markets, meaning replacements sourced to those regional standards will conform to the same electrical and physical specifications as the originals.
