The Suzuki Motorcycle VL1500 Intruder uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1998 through 2004 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 9003 bulb is the sole headlight bulb type specified for the Suzuki Motorcycle VL1500 Intruder across all listed model years.
Both the high beam and low beam headlight positions on the VL1500 Intruder use the same 9003 bulb for the 1998-2004 model years.
The 9003 is a dual-filament halogen bulb, meaning a single physical bulb contains two separate filaments to serve both high and low beam functions within one housing.
The 9003 operates at 12 volts and carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange, and fitment requires a socket compatible with this specific base type.
The 9003 designation follows the ANSI standard used in the United States and Canada. It is electrically and physically equivalent to the European H4 bulb, though the two designations originate from different standardization bodies.
Because the 9003 and H4 share the same dual-filament configuration, P43t base, and voltage and wattage ratings, they are generally considered interchangeable in practice, though the specifications listed here reference only the 9003 designation.
