The Toyota FJ Cruiser brake bulb uses a 7443 size for both inner and outer brake applications. The replacement chart covers vehicle production from 2007 to 2014 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 Toyota FJ Cruiser uses the 7443 bulb across all brake light positions covered in these specifications, spanning the 2007-2014 model years.
The 7443 is an ANSI-standard bulb recognized in the United States and Canada, making it a widely available replacement type in North American markets.
The 7443 follows the T20 wedge form factor, which refers to a wedge-base bulb with a 20mm wide tip, seated without a metal screw base.
As a dual-filament bulb, the 7443 operates at two wattage levels: 21W for the high-intensity brake function and 5W for the lower-intensity running light function, both at 12 volts.
The outer brake position on the 2014 Toyota FJ Cruiser carries a production cutoff of July 2014, meaning vehicles built after that date fall outside the scope of this fitment entry.
The outer brake position on the 2011 Toyota FJ Cruiser carries a production cutoff of November 2010, indicating that this fitment applies only to early-production 2011 model year vehicles.
The 7443 bulb is not interchangeable with the 7440, which shares the same T20 wedge base but is a single-filament type. Installing a 7440 in a dual-filament socket would result in the loss of one lighting function.
