The Ski-Doo Summit 700 uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2000 to 2003 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 the sole bulb type listed across all headlight positions in the Ski-Doo Summit 700 specifications, covering model years 2000, 2001, and 2003.
The 9003 is a dual-filament halogen bulb, meaning a single unit contains separate filaments for both high and low beam operation. This is why the same bulb size appears under both the high beam and low beam headlight categories for the Summit 700.
The 9003 operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm collar. Bulbs with differing base types are not physically interchangeable with this fitting, regardless of wattage similarity.
The 9003 is defined under the ANSI standard as used in the United States and Canada. It is functionally equivalent to the European ECE-rated H4 bulb, though the two designations originate from different regulatory frameworks and packaging may differ by market.
Because the 9003 serves both beam functions through its dual filaments, the headlight assembly on the Ski-Doo Summit 700 (2000-2003) relies on a single bulb socket per lamp rather than separate sockets for each beam mode.
