The Kawasaki VN2000 Vulcan 2000 Classic uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2006 to 2010 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 Kawasaki VN2000 Vulcan 2000 Classic uses the 9003 bulb for both its high beam and low beam headlight positions across the 2006-2010 model years.
The 9003 is an ANSI-standardized bulb type recognized in the United States and Canada, distinguishing it from the visually similar H4 bulb, which follows ECE standards used in other markets.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments, one dedicated to the high beam function and one to the low beam function.
The bulb operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a three-pronged bayonet-style mount with a 43mm collar, and this base type is shared with the H4 bulb.
Although the 9003 and H4 share the same P43t base and are physically interchangeable in many cases, they are governed by different standards bodies, and substitution may affect compliance depending on the regulatory context.
Because the same 9003 bulb serves both the high and low beam positions, the VN2000 Vulcan 2000 Classic requires only one bulb type to service the entire headlight assembly.
