Ski-Doo MX Z 600 high beam and low beam headlight bulbs both utilize a 9003 size. The replacement chart covers vehicle production spanning 1999 to 2011.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ski-Doo MX Z 600 uses the 9003 bulb size for both high beam and low beam headlights across the 1999-2011 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both the high beam and low beam functions.
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, and this base type determines physical fitment into the headlight housing.
The 9003 designation follows the ANSI standard as used in the United States and Canada, and it is functionally equivalent to the European H4 bulb, though the two designations originate from different regional standards bodies.
Because the same 9003 bulb serves both beam functions in the MX Z 600, replacing one bulb affects both the high and low beam output for that headlight position.
