The Kawasaki VN900 Vulcan 900 headlight bulb uses a 9003 size for both high and low beam functions. The replacement chart covers vehicle production spanning 2006 to 2023.
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 Kawasaki VN900 Vulcan 900 across all listed model years, covering both the high beam and low beam positions from 2006-2023.
The 9003 is a dual-filament halogen bulb, meaning a single physical bulb contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
Because the 9003 serves both the high beam and low beam functions within one unit, the VN900 Vulcan 900 uses the same bulb part number for both headlight positions rather than two distinct bulb types.
The 9003 operates on a 12V electrical system and uses a P43t base, which is a bayonet-style mount with a 43mm collar that physically determines socket compatibility.
The 9003 designation follows the ANSI standard used in the United States and Canada. It is electrically and physically equivalent to the H4 bulb used under European and international standards, making cross-reference between these two designations applicable for fitment purposes.
The P43t base is a keyed fitting, meaning the bulb can only be seated in one orientation. This prevents incorrect filament alignment, which would otherwise direct high and low beam light output to the wrong positions within the headlight reflector housing.
