The Suzuki Motorcycle TL1000R uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 1998 to 2003 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 Suzuki Motorcycle TL1000R uses the 9003 bulb size for both high beam and low beam headlight positions across all model years from 1998-2003.
The 9003 is an ANSI-standard bulb designation recognized in the United States and Canada, making it the North American equivalent of what is internationally classified as the H4 bulb type.
The 9003 bulb is a dual-filament halogen type, meaning a single bulb unit contains two separate filaments, one dedicated to high beam output and one to low beam output.
The bulb operates on a 12-volt electrical system and carries a wattage rating of 60W for the high beam filament and 55W for the low beam filament.
The 9003 bulb uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type is a physical fitment standard, and bulbs with a different base type are not interchangeable with this socket.
Because both the high beam and low beam positions share the same 9003 specification, the TL1000R uses a single bulb to serve both lighting functions rather than separate bulbs for each beam.
