Suzuki Motorcycle VZ800 Marauder high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 1997 to 2004.
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 headlight bulb type specified for the Suzuki Motorcycle VZ800 Marauder across all listed model years, covering both the high beam and low beam positions for 1997-2004.
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 on the VZ800 Marauder use the same 9003 bulb, a single replacement bulb type serves both functions on this motorcycle.
The 9003 bulb operates on a 12-volt electrical system and uses a P43t base, which is a bayonet-style mount with a 43mm flange that physically determines fitment into the headlight housing.
The 9003 designation is an ANSI standard recognized in the United States and Canada. It is electrically and functionally equivalent to the European H4 bulb, though the two standards differ in base construction and are not always physically interchangeable without an adapter.
The P43t base on the 9003 is specific to that standard and is not compatible with single-filament bases such as the P14.5s used on H1 or H7 bulbs, making base type a critical factor in fitment.
