The Ski-Doo GSX 900 uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2014 to 2015 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 bulb type specified for both the high beam and low beam headlight positions on the Ski-Doo GSX 900 across the 2014-2015 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.
The 9003 operates on a 12V electrical system and uses a P43t base, which is a bayonet-style mount with a 43mm collar.
The 9003 follows the ANSI standard, which is the designation used in the United States and Canada, and is functionally equivalent to the H4 designation used under European ECE standards, though fitment should be confirmed before substitution.
Because the 9003 serves both beam functions in a single housing, the high beam and low beam headlight positions on this vehicle share an identical bulb specification rather than requiring separate bulb types for each function.
