The Ski-Doo Summit 800 Adrenaline uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2003 through 2008 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 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments to produce both high and low beam output from one unit.
The Ski-Doo Summit 800 Adrenaline uses the 9003 bulb for both its high beam and low beam headlight positions across the 2003-2008 model years.
Because both beam positions share the same bulb type, a single 9003 unit serves the full headlight function rather than requiring separate bulbs for each beam.
The 9003 operates at 12 volts and draws 60 watts on the high beam filament and 55 watts on the low beam filament, reflecting the higher power demand of high beam output.
The P43t base is the physical mounting interface of the 9003 bulb, a bayonet-style base that locks the bulb into the headlight housing.
The 9003 designation follows ANSI standards as applied in the United States and Canada, making it the North American equivalent of what is internationally designated as the H4 bulb type.
While the 9003 and H4 share the same physical construction and electrical ratings, they are defined under different standardization systems, and fitment compatibility between the two designations warrants verification before substitution.
