The Yamaha XVZ1300 Royal Star headlight bulb uses a 9003 size for both high and low beam functions. The replacement chart covers vehicle production years spanning 1996 to 2009.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Yamaha XVZ1300 Royal Star uses the 9003 bulb size for both high beam and low beam headlight positions across the 1996-2001 and 2005-2009 model years.
The 9003 is an ANSI-standard halogen bulb recognized in the United States and Canada, operating on a 12-volt system with a dual-filament design rated at 60 watts for high beam and 55 watts for low beam.
Because the 9003 contains two filaments within a single housing, one bulb serves both the high beam and low beam functions, which is reflected in the specifications listing the same part number for both positions.
The 9003 bulb uses a P43t base, a bayonet-style mount with a 43mm collar, which determines physical fitment into the headlight socket and is not interchangeable with other base types without modification.
The 9003 designation is the ANSI equivalent of the international H4 bulb; while the two are functionally similar, differences in base tolerances between the standards can affect fitment, and substitution between them is not always straightforward.
