Suzuki Motorcycle VL800 Intruder Volusia headlight bulbs utilize a 9003 size for both high and low beam functions. The replacement chart covers 2001 through 2004 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 across all headlight positions on the Suzuki Motorcycle VL800 Intruder Volusia, covering model years 2001-2004 for both high beam and low beam functions.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments: one rated at 60 watts for high beam output and one rated at 55 watts for low beam output.
Because both the high beam and low beam positions share the same 9003 specification, the VL800 Intruder Volusia uses a single bulb to serve both lighting functions rather than separate bulbs for each.
The 9003 designation follows the ANSI standard used in the United States and Canada. It is functionally equivalent to the international HB2 designation, and both share the same P43t base and electrical ratings.
The P43t base is a bayonet-style mount with a 43mm collar, and its three offset tabs are positioned to allow only one correct insertion orientation, which prevents incorrect filament alignment during installation.
The 9003 and H4 bulb types are physically interchangeable due to identical base and filament geometry, though they carry different designation systems reflecting their respective regional standards.
