Honda Motorcycle CB900F 919 headlight bulbs utilize a 9003 size for both high and low beam functions. The replacement chart covers 2002 through 2007 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 Honda Motorcycle CB900F 919 uses the 9003 bulb size across all model years from 2002-2007 for both high beam and low beam headlight positions.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both the high beam and low beam functions within one housing.
The 9003 bulb 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 bayonet-style mount with a 43mm flange. This base type determines physical fitment into the headlight housing and is not interchangeable with other base configurations.
The 9003 designation follows the ANSI standard used in the United States and Canada. It is functionally equivalent to the H4 bulb used under international IEC standards, though the designations originate from different standardization bodies.
Because the same 9003 bulb specification applies to both the high beam and low beam positions across all six model years, a single bulb type covers the entire headlight assembly of the CB900F 919.
