The Kawasaki VN1700 Vulcan 1700 Nomad uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 2009 to 2013 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 Nomad uses the 9003 bulb for both the high beam and low beam headlight positions across the 2009-2013 model years.
The 9003 is an ANSI-standard bulb recognized in the US 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 a single 9003 bulb serves both the high and low beam functions, the two filaments within one housing handle both lighting modes rather than requiring separate bulbs for each position.
The 9003 bulb uses a P43t base, which is a bayonet-style mount with a 43mm collar. This base type determines physical fitment and is not interchangeable with other base configurations even when voltage and wattage ratings may otherwise align.
The H4 bulb is the international equivalent of the 9003 and shares the same dual-filament halogen construction and P43t base, though the ANSI 9003 designation is the applicable standard for the North American market.
The consistent use of the 9003 across all five model years and both beam positions means a single bulb specification covers the entire headlight assembly for the 2009-2013 production run.
