Harley-Davidson XL1200S Sportster 1200 Sport Headlight Bulb Size
Harley-Davidson XL1200S Sportster 1200 Sport headlight bulb uses 9003 size for both high and low beam functions. The replacement chart covers 1996 to 2003 model years 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 Harley-Davidson XL1200S Sportster 1200 Sport uses the 9003 bulb size for both high beam and low beam headlight positions across the 1996-2003 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both the high beam and low beam functions independently.
The bulb operates on a 12-volt electrical system and carries 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 bayonet-style mount with a 43mm collar, and this base type determines physical fitment into the headlight housing.
The 9003 designation follows the ANSI standard applicable in the United States and Canada, which defines the bulb's electrical and mechanical specifications within those markets.
The 9003 and H4 bulbs share the same dual-filament halogen design and P43t base, though the 9003 is the ANSI-designated version while H4 follows the ECE standard used in other regions; substitution between these types warrants attention to the specific standard required by the application.
