The Ski-Doo Expedition Sport high beam and low beam headlight bulbs both utilize a 9003 size. The replacement chart covers 2006 through 2019 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 unit contains two separate filaments: one rated at 60W for high beam operation and one rated at 55W for low beam operation.
The Ski-Doo Expedition Sport uses the 9003 bulb size for both the high beam and low beam headlight positions across the 2006-2019 model years covered in these specifications, with no variation between positions or years.
The 9003 operates on a 12V electrical system, which is standard for most powersport and automotive applications in this category.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm collar. This base type is a physical fitment factor, as bulbs with differing base types are not interchangeable regardless of wattage or voltage compatibility.
The 9003 is designated as an ANSI standard bulb applicable in the United States and Canada. It is functionally equivalent to the H4 bulb used under European ECE standards, sharing the same dual-filament design and P43t base, though the two designations reflect different regulatory frameworks.
Because the 9003 serves both beam functions within a single housing, replacing the bulb affects both high and low beam output simultaneously.
