The Yamaha XJ650L Turbo Seca headlight bulb utilizes a 9003 size for both high and low beam functions. The replacement chart covers 1982 to 1983 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 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments to serve both high beam and low beam functions independently.
The 9003 operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The P43t base designation refers to a prefocus bayonet-style base with a 43mm collar, a standardized mounting format used to ensure consistent optical alignment within the headlight housing.
The 9003 is defined under ANSI standards and is the designation used in the United States and Canada, making it the applicable specification for those markets.
The Yamaha XJ650L Turbo Seca uses the 9003 bulb for both the high beam and low beam headlight positions across the 1982-1983 model years.
Because the high beam and low beam positions both use the 9003, a single bulb type serves the entire headlight assembly rather than requiring separate bulbs for each function.
The 9003 shares its physical base and filament configuration with the H4 bulb, though the two designations reflect different regional standards; the H4 is the ECE designation used outside North America, while the 9003 is the ANSI equivalent.
