Suzuki Motorcycle SV1000/S headlight bulbs utilize a 9003 size for both high and low beam functions. The replacement chart covers 2003 through 2007 production 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 Suzuki Motorcycle SV1000/S uses the 9003 bulb size for both the high beam and low beam headlight positions across the 2003-2007 model years.
The 9003 is an ANSI-standard bulb designation recognized in the United States and Canada, making it a regionally standardized specification rather than a proprietary or manufacturer-specific size.
The 9003 bulb is a dual-filament halogen type, meaning a single bulb unit contains two separate filaments that serve the high beam and low beam functions independently.
The 9003 bulb operates on 12 volts and carries a wattage rating of 60W for the high beam filament and 55W for the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm collar. This base type determines physical fitment and is not interchangeable with bulbs that use different base configurations.
Because the same 9003 bulb specification applies to both the high beam and low beam positions, the SV1000/S headlight assembly relies on the bulb's dual-filament design rather than separate single-filament bulbs for each function.
The 9003 designation is the ANSI equivalent of the internationally designated HB2 bulb. Products sold under either designation share the same electrical and physical specifications, though labeling may vary by market.
