The Ski-Doo MX Z 1200 uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2009 to 2011 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 on the Ski-Doo MX Z 1200 for the 2009-2011 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.
Because the 9003 serves both the high beam and low beam positions on this vehicle, the same physical bulb handles both lighting functions rather than requiring separate bulbs for each.
The 9003 uses a P43t base, which is a bayonet-style fitting with a 43mm flange. This base type determines physical compatibility with the headlight housing and is not interchangeable with other base configurations.
The 9003 operates on a 12V electrical system, which is standard for powersports vehicles of this type.
The 9003 follows the ANSI standard as used in the United States and Canada. It is functionally equivalent to the H4 bulb used under European ECE standards, though the designations reflect different regulatory frameworks and the two are not always interchangeable depending on housing design.
