The Ski-Doo Summit 800 Everest uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2007 through 2010 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 Ski-Doo Summit 800 Everest uses the 9003 bulb across both its high beam and low beam headlight positions for the 2007-2010 model years.
The 9003 is an ANSI-standardized bulb type recognized in the United States and Canada, operating on a 12-volt electrical system with a dual-filament halogen design rated at 60 watts for high beam and 55 watts for low beam.
The dual-filament construction of the 9003 allows a single bulb to serve both the high and low beam functions, which accounts for its use in both headlight positions on this vehicle.
The 9003 bulb uses a P43t base, a bayonet-style mount with a 43mm collar, which determines physical fitment into the headlight housing.
The 9003 and H4 bulb types share the same P43t base and dual-filament halogen configuration, though the 9003 designation follows ANSI standards while H4 follows ECE standards used in Europe; these types are often cross-compatible but the specifications list only the 9003 designation for this vehicle.
