Suzuki Motorcycle SV650 high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 1999 to 2019.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 is the sole bulb type specified across all listed model years of the Suzuki Motorcycle SV650, covering both the high beam and low beam headlight positions from 1999-2009 and 2017-2019.
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.
Because both the high beam and low beam positions share the same 9003 specification, the SV650 uses a single bulb to serve both lighting functions rather than separate bulbs for each beam.
The 9003 operates on a 12V electrical system, which is standard for motorcycle applications of this type.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type is specific to the 9003 and its international equivalent, the H4, and is not interchangeable with single-filament bases such as those found on 9005 or 9006 bulbs.
The 9003 and H4 bulbs share the same physical base and filament configuration, making them functionally equivalent. The 9003 designation is the ANSI standard used in the United States and Canada, while H4 is the ECE designation used in other markets.
