The Ski-Doo Tundra Sport high beam and low beam headlight bulb size is 9003 for both applications. The replacement chart covers 2012 to 2019 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 Ski-Doo Tundra Sport uses the 9003 bulb size for both high beam and low beam headlight positions across the 2012-2019 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments to serve both the high beam and low beam functions within one unit.
The 9003 operates at 12 volts 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 flange. 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 physical characteristics under a standardized classification system.
The 9003 and H4 bulbs share the same dual-filament halogen design and P43t base, and are electrically equivalent. However, the 9003 follows ANSI standards while the H4 follows ECE standards, and subtle differences in filament positioning between the two can affect beam pattern alignment in some housings.
