The Bimota SB8 headlight bulb uses a 9003 size for both high beam and low beam applications. The replacement chart covers 2000 to 2001 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 the sole bulb type specified for the Bimota SB8 across both the 2000-2001 model years, covering 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: one rated at 60W for high beam output and one rated at 55W for low beam output.
Operating voltage for the 9003 is 12V, which is consistent with standard 12-volt automotive and motorcycle electrical systems.
The 9003 uses a P43t base, a bayonet-style mount that physically determines fitment. Bulbs with differing base types are not interchangeable with this socket regardless of voltage or wattage compatibility.
The 9003 designation follows ANSI standards applicable in the United States and Canada. It is functionally equivalent to the European H4 bulb, though the two designations originate from different standardization bodies and packaging may differ.
Because the 9003 serves both the high beam and low beam positions on the Bimota SB8, both functions are lost if the single bulb fails, unlike systems that use separate single-filament bulbs for each function.
