The Yamaha SRX600 headlight bulb uses a 9003 size for both high beam and low beam applications. The replacement chart covers vehicle production years from 1998 to 1999 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 bulb is a dual-filament halogen type, meaning a single bulb contains two separate filaments to serve both high and low beam functions independently.
The 9003 operates at 12 volts, with a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, which is a standardized bayonet-style fitting with a 43mm flange width.
The 9003 designation follows the ANSI standard used in the United States and Canada, distinguishing it from visually similar bulbs sold under different regional standards.
The Yamaha SRX600 uses the 9003 bulb for both the high beam and low beam headlight positions across the 1998-1999 model years.
Because the 9003 serves both beam functions in the SRX600, the high beam and low beam headlight sockets accept the same bulb type, which reflects a single-bulb headlight system rather than a separate dual-bulb arrangement.
The 9003 is functionally equivalent to the H4 bulb used in international markets, though the two designations originate from different standards bodies and packaging may differ by region.
