Toyota FJ Cruiser front turn signal bulbs use 1157 size while rear turn signal bulbs use 7440NA size. The replacement chart covers vehicle production years spanning 2007 to 2014.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Toyota FJ Cruiser uses the 1157 bulb for the front turn signal across all model years from 2007-2014.
The 1157 is a dual-filament bulb, meaning it carries two separate filaments within a single housing, rated at 21W for the high-intensity filament and 5W for the low-intensity filament.
It operates on a 12V system and uses a BAY15d bayonet base, a two-pin offset base design that prevents incorrect installation orientation.
The dual-filament nature of the 1157 makes it suitable for combined turn signal and parking light functions within a single bulb position.
The rear turn signal on the FJ Cruiser uses the 7440NA across all model years from 2007-2014.
The 7440NA is a single-filament T20 wedge bulb rated at 21W, distinguished from the standard 7440 by its natural amber glass envelope, which produces an amber output without relying on a colored lens.
Because the 7440NA produces its amber color through the glass itself, substituting a clear 7440 in its place would alter the color output at the rear turn signal position.
The front and rear turn signals on the FJ Cruiser use physically incompatible base types, the BAY15d bayonet for the front and the T20 wedge for the rear, making the two bulbs non-interchangeable with each other.
Both bulb types conform to ANSI standards applicable in the United States and Canada.
Both the 1157 and 7440NA operate at 12V, consistent with the standard electrical system voltage found in passenger vehicles.
