Toyota Sequoia front side marker bulbs use 168 or 3157NA bulb sizes, while rear side marker bulbs require 7443 bulb size. The replacement chart covers 2001 through 2019 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 168 bulb is a miniature T10 wedge type rated at 12V and 4.9W, making it one of the lower-wattage bulbs in these specifications. It serves as the front side marker on the Toyota Sequoia for model years 2008-2018.
The 3157NA is a dual-filament T25 wedge bulb rated at 12V with a 27W high filament and a 7W low filament. Its natural amber glass produces a yellow-tinted output without requiring a separate amber lens or colored housing. This bulb covers the front side marker position on the Sequoia for model years 2001-2007.
The front side marker position transitioned from the 3157NA to the 168 between the 2007 and 2008 model years. These two bulbs are not interchangeable, as they differ in base type, filament count, wattage, and glass color.
The 7443 is a dual-filament T20 wedge bulb rated at 12V with a 21W high filament and a 5W low filament. It is the sole bulb type specified for the rear side marker position across all listed model years.
The 3157NA and 7443 are both dual-filament wedge bulbs, but they use different base sizes, T25 and T20 respectively, and carry different wattage ratings. They are not interchangeable with each other or with the single-filament 168.
For the 2019 model year, the rear side marker bulb size of 7443 carries a fitment note specifying it applies to vehicles with the High Efficiency Twin Cam engine. No equivalent conditional note appears for any other model year in the rear side marker data.
