Yamaha RXW10 RX Warrior high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers 2004-2005 vehicle production 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 9003 is an ANSI-standard dual-filament halogen bulb rated at 12 volts, with a high beam filament drawing 60 watts and a low beam filament drawing 55 watts. It uses a P43t base.
Because the 9003 carries two filaments within a single housing, it serves both the high beam and low beam functions from one bulb per headlight assembly.
The Yamaha RXW10 RX Warrior uses the 9003 bulb for both the high beam and low beam headlight positions across the 2004-2005 model years.
The P43t base is a bayonet-style mount with a 43mm flange, and it is the physical interface that determines whether a replacement bulb will seat correctly in the headlight housing.
The 9003 designation is specific to the ANSI standard used in the United States and Canada. The functionally equivalent European designation is H4, though labeling and packaging differences exist between the two standards and substitution should be confirmed before use.
