Honda Motorcycle CB750F Super Sport Headlight Bulb Size
Honda Motorcycle CB750F Super Sport headlight bulbs utilize a 9003 size for both high beam 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 60W high beam filament and a 55W low beam filament, mounted on a P43t base. Its dual-filament design allows a single bulb to serve both beam functions from one housing.
The Honda Motorcycle CB750F Super Sport uses the 9003 bulb for both the high beam and low beam headlight positions across the 1981-1982 model years, meaning one bulb type handles both lighting functions in the headlight assembly.
The 9003 designation follows the ANSI standard as recognized in the United States and Canada. This standardization means the bulb specification is defined by a regulatory body rather than solely by the manufacturer.
The P43t base is a bayonet-style mount with a 43mm collar, which physically determines fitment compatibility. A bulb with a different base type will not seat correctly in a socket designed for the P43t format, regardless of voltage or wattage ratings.
Because the same 9003 bulb specification applies to both the high beam and low beam positions, the two headlight sockets on the CB750F Super Sport accept the same replacement bulb, with no distinction between the two positions at the part number level.
