Ski-Doo GTX 600 high beam and low beam headlight bulbs both utilize a 9003 bulb size for optimal illumination. The replacement chart covers 2005 through 2009 model years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ski-Doo GTX 600 uses the 9003 bulb for both the high beam and low beam headlight positions across the 2005-2009 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
Operating voltage for the 9003 is 12V, consistent with standard 12-volt electrical systems found in powersports applications.
The 9003 bulb uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type determines physical fitment into the headlight housing and is not interchangeable with other base configurations.
The 9003 designation follows the ANSI standard used in the United States and Canada. It is functionally equivalent to the European H4 bulb, though the two designations originate from different standardization bodies and packaging may vary by market.
Because the same 9003 bulb serves both the high beam and low beam positions, the GTX 600 headlight assembly relies on a single bulb per housing rather than separate bulbs for each function.
