The Yamaha XVS1100 V Star 1100 headlight bulb uses a 9003 size for both high and low beam functions. The replacement chart covers 1999 to 2009 production years 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 Yamaha XVS1100 V Star 1100 uses the 9003 bulb size for both the high beam and low beam headlight positions across the entire 1999-2009 model range.
The 9003 is an ANSI-standard halogen bulb recognized in the United States and Canada, operating on a 12-volt electrical system with a dual-filament 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 specification, a single bulb type serves both functions through its two 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 and is not interchangeable with other base configurations even when voltage and wattage ratings may otherwise match.
The 9003 designation is the ANSI equivalent of the internationally designated H4 bulb. While these two designations are functionally and physically equivalent, regional labeling differences mean the same bulb may be sold under either name depending on the market.
