Honda Motorcycle CBR600F F4 uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1999 to 2000 model 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 9003 bulb is an ANSI-standard halogen type used in the United States and Canada, operating on a 12-volt system with a dual-filament design rated at 60 watts for high beam and 55 watts for low beam.
The dual-filament construction of the 9003 allows a single bulb to serve both high and low beam functions, which is reflected in the Honda Motorcycle CBR600F F4 using the same bulb size for both beam positions.
The 9003 bulb uses a P43t base, a bayonet-style mount that physically determines socket compatibility and is not interchangeable with other base types without modification.
Both the 1999-2000 model years share identical bulb specifications across high and low beam positions, with the 9003 specified for all four fitment positions across those two years.
