The Yamaha SX600/R headlight bulb uses a 9003 size for both high beam and low beam applications. The replacement chart covers vehicle production years spanning 2000 to 2003.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the sole bulb type specified across all headlight positions on the Yamaha SX600/R for the 2000-2003 model years.
The 9003 is an ANSI-standard halogen bulb recognized in the United States and Canada, operating on a 12-volt electrical system.
As a dual-filament bulb, the 9003 houses two separate filaments within a single housing, one rated at 60 watts for high beam output and one at 55 watts for low beam output.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm collar, which physically determines socket compatibility during replacement.
Because the 9003 serves both the high beam and low beam positions on the Yamaha SX600/R, a single bulb type handles both lighting functions rather than requiring separate bulbs for each circuit.
The 9003 is functionally equivalent to the H4 bulb used in international markets, sharing the same dual-filament design and P43t base, though the 9003 designation reflects the ANSI classification system specific to North America.
Substituting a single-filament bulb in either headlight position would be incompatible, as the socket and wiring on the SX600/R are configured for the dual-filament 9003 format.
