Honda Motorcycle CB900F Super Sport Headlight Bulb Size
Honda Motorcycle CB900F Super Sport headlight bulbs utilize a 9003 size for both high and low beam functions. The replacement chart covers 1981 to 1982 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 is a dual-filament halogen bulb operating at 12 volts, with a 60-watt filament for high beam and a 55-watt filament for low beam. It uses a P43t base and conforms to the ANSI standard applicable in the United States and Canada.
The Honda Motorcycle CB900F Super Sport uses the 9003 bulb for both the high beam and low beam headlight positions across the 1981-1982 model years.
Because the 9003 serves both beam functions, the high and low beam outputs are produced by separate filaments within a single bulb housing rather than by two separate bulbs.
The P43t base is a bayonet-style mount with a 43mm cap, which physically determines bulb fitment and is not interchangeable with other base types such as H4 or P45t without modification.
The 9003 and H4 bulb types share the same dual-filament halogen design and identical wattage ratings, but the H4 follows ECE regulations used outside North America while the 9003 follows ANSI standards. The two designations are often treated as functionally equivalent, though regulatory compliance differs by market.
