The Ski-Doo Summit 800 Sport uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2002 to 2004 production 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 9003 is a dual-filament halogen bulb operating at 12 volts, with a high beam output of 60 watts and a low beam output of 55 watts. It uses a P43t base and conforms to the ANSI standard recognized in the United States and Canada.
Because the 9003 carries two filaments within a single housing, it serves both the high beam and low beam functions from one bulb unit. The Ski-Doo Summit 800 Sport applies this characteristic across both beam positions for the 2002 and 2004 model years.
The 9003 standard is the North American ANSI designation. It is electrically and physically equivalent to the international HB2 designation, which means bulbs sold under either designation are generally interchangeable, provided the P43t base is present.
The P43t base features a three-pronged bayonet-style mount with a 43mm collar. This base type is not compatible with single-filament sockets or bases of differing collar sizes, making base verification relevant before substitution.
