The Ski-Doo MX Z X-RS 600 uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2009 through 2016 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 bulb is the sole bulb type specified across all headlight positions for the Ski-Doo MX Z X-RS 600, covering model years 2009-2016.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both high beam and low beam functions from one housing position.
The 9003 operates on a 12-volt electrical system and carries a wattage rating of 60W on the high beam filament and 55W 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 used in the United States and Canada, which defines the bulb's electrical and mechanical specifications under a standardized classification system.
Because the same 9003 bulb serves both the high beam and low beam positions, the two circuits draw from the same physical bulb, and a single bulb failure affects both beam modes simultaneously.
The 9003 is functionally equivalent to the H4 bulb type used under European ECE standards, though the two designations originate from different regulatory frameworks and may carry minor specification differences that affect direct interchangeability.
