The Kawasaki VN1700 Vulcan 1700 Vaquero headlight uses a 9003 bulb size for both high beam and low beam applications. The replacement chart covers 2011 through 2022 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 VN1700 Vulcan 1700 Vaquero uses the 9003 bulb for both its high beam and low beam headlight positions across the 2011-2022 model years.
The 9003 is an ANSI-standardized bulb type recognized in the United States and Canada, operating on a 12-volt electrical system with a dual-filament halogen design rated at 60 watts for high beam and 55 watts for low beam.
Because both the high beam and low beam positions share the same 9003 bulb, a single bulb type serves both lighting functions through its two internal filaments rather than requiring separate bulbs for each beam.
The 9003 bulb uses a P43t base, which is a bayonet-style mount with a 43mm collar. This base type determines physical fitment into the headlight housing and is not interchangeable with other base configurations.
The 9003 designation is the ANSI equivalent of the internationally used H4 bulb. While the two types share the same filament configuration and base, they are subject to different regulatory standards, and substitution between them warrants attention to regional compliance requirements.
