The Kawasaki VN800 Vulcan 800 headlight bulb uses a 9003 size for both high and low beam functions. The replacement chart covers vehicle production spanning 1995 to 2006 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Kawasaki VN800 Vulcan 800 uses the 9003 bulb size for both high beam and low beam headlight positions across all model years from 1995-2006.
The 9003 is an ANSI-standardized bulb designation used in the United States and Canada, operating on a 12-volt electrical system with a dual-filament halogen design rated at 60 watts on high beam and 55 watts on low beam.
The dual-filament construction of the 9003 allows a single bulb to serve both the high and low beam functions, which is consistent with the VN800 Vulcan 800 sharing the same bulb specification across both headlight positions.
The 9003 bulb uses a P43t base, a bayonet-style mount with a 43mm collar. This base type is specific to the 9003 and its international equivalent, the H4, and is not interchangeable with single-filament base types such as the P14.5s used in 9005 or 9006 bulbs.
The H4 bulb is the international equivalent of the 9003 and shares the same P43t base and 60W/55W dual-filament configuration. The two designations refer to the same physical bulb under different regional naming standards.
