Ski-Doo Summit X T3 Package E-TEC 800R Headlight Bulb Size
The Ski-Doo Summit X T3 Package E-TEC 800R uses 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2015 to 2016 model 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 a dual-filament halogen type, meaning a single bulb contains two separate filaments that serve distinct functions. One filament operates at 60 watts for high beam output, while the other operates at 55 watts for low beam output.
The 9003 designation follows the ANSI standard used in the United States and Canada. It is electrically and physically equivalent to the H4 bulb used under European standards, though the designations differ by market.
The 9003 bulb uses a P43t base, which is a three-pronged bayonet-style mount. This base type is specific to dual-filament halogen bulbs and is not interchangeable with single-filament base types such as the P14.5s or P22d.
The Ski-Doo Summit X T3 Package E-TEC 800R uses the 9003 bulb for both the high beam and low beam headlight positions across the 2015-2016 model years. A single bulb type serves both functions simultaneously through its dual-filament construction.
Because the high beam and low beam share the same 9003 bulb, replacing one position requires the same part as the other. There is no separate bulb size for each beam function on this vehicle.
The 9003 operates on a 12-volt electrical system, which is standard for powersports and automotive applications. The wattage values of 60W and 55W reflect the power draw at each filament independently, not simultaneously.
