The Suzuki Motorcycle TL1000S headlight bulb uses a 9003 size for both high beam and low beam functions. The replacement chart covers vehicle production years spanning 1997 to 2001.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Suzuki Motorcycle TL1000S uses the 9003 bulb for both its high beam and low beam headlight positions across all model years from 1997-2001.
The 9003 is an ANSI-standard designation used in the United States and Canada, making it the applicable specification for those markets.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments to serve both high and low beam functions within one housing.
The bulb 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 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type determines physical fitment into the headlight housing.
Because both the high beam and low beam positions share the same 9003 specification, a single bulb type serves the entire headlight assembly on this motorcycle.
The 9003 bulb is internationally equivalent to the H4 designation. However, the H4 and 9003 share the same base and filament configuration, though they may carry different certification markings depending on the market.
