The Toyota FJ Cruiser outer tail light and tail light utilize a 7443 bulb size for replacement applications. The replacement chart contains specifications covering 2007 to 2014 vehicle production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 7443 is the sole bulb type listed across all outer tail light positions for the Toyota FJ Cruiser, covering model years 2007-2014.
The 7443 is an ANSI-standard bulb recognized in the United States and Canada, classified under the T20 wedge form factor with a dual-filament design operating at 12 volts and rated at 21W/5W.
The dual-filament configuration of the 7443 allows it to serve two brightness levels within a single housing, which is typical for combined stop and tail light functions.
The 21W filament generally corresponds to the higher-intensity stop light function, while the 5W filament serves the lower-intensity running or tail light function.
The T20 wedge base of the 7443 does not use a metal pin connector, relying instead on the tapered plastic wedge body to make electrical contact within the socket.
A production date qualifier applies to the 2011 model year outer tail light, where the 7443 fitment is noted as applicable from November 2010 onward.
A production date qualifier also applies to the 2014 model year, where the 7443 fitment is noted as applicable through July 2014.
The 7443 shares the same T20 wedge base as the related 7440 bulb, but the 7440 is a single-filament type; substituting a 7440 in place of a 7443 would result in the loss of one lighting function.
