The Toyota FJ Cruiser headlight bulb uses a 9003 size for both high beam and low beam applications. 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 9003 bulb for both high beam and low beam headlights across all model years from 2007-2014.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments to serve both the high beam and low beam functions within one unit.
Because the 9003 handles both beam functions simultaneously, the FJ Cruiser does not require separate bulbs for high and low beam operation.
The 9003 operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a standardized bayonet-style connector that determines physical fitment into the headlight housing.
The 9003 is an ANSI-standardized bulb type recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications.
The 9003 is electrically equivalent to the H4 bulb, which is the international designation for the same dual-filament halogen type, though the two designations originate from different standardization bodies and may carry minor physical differences that affect interchangeability.
The consistent use of the 9003 across every model year from 2007-2014 indicates no headlight bulb specification changes were made throughout the FJ Cruiser's production run.
