Suzuki Motorcycle SFV650 uses 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2013 to 2015 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 type specified across all headlight positions on the Suzuki Motorcycle SFV650 for the 2013-2015 model years, serving both high beam and low beam functions.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
Because both filaments are housed in one unit, the high beam and low beam headlight positions on the SFV650 use the same physical bulb, which accounts for the identical 9003 specification across both sub-parts.
The 9003 bulb operates on a 12V electrical system and uses a P43t base, which is a bayonet-style mount with a 43mm collar width.
The 9003 designation follows the ANSI standard used in the United States and Canada. It is electrically and functionally equivalent to the H4 bulb used under European and international standards, though the designations originate from different standardization bodies.
The P43t base is not interchangeable with other common motorcycle headlight bases such as the P14.5s used in single-filament H1 bulbs, making base compatibility a relevant factor when sourcing a replacement.
