The Ski-Doo MX Z X-RS headlight bulb specifications include 9008 and 9003 sizes for both high and low beam applications. A replacement chart covering 2011 through 2019 model years documents the bulb size data for this snowmobile.
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 operating at 12V with a 60W high beam filament and a 55W low beam filament. It uses a P43t base and meets ANSI standards for the US and Canada.
The 9008 bulb is also a dual-filament halogen type operating at 12V, rated at 65W for the high beam filament and 55W for the low beam filament. It uses a P26t base and likewise meets ANSI standards for the US and Canada.
The primary distinction between the 9003 and 9008 bulbs lies in their base type and high beam wattage. The 9003 uses a P43t base at 60W high beam, while the 9008 uses a P26t base at 65W high beam. These differing base types make the two bulbs physically non-interchangeable.
The Ski-Doo MX Z X-RS used the 9003 bulb for both the high beam and low beam headlights across the 2011-2018 model years.
For the 2019 model year, both the high beam and low beam headlight positions shifted to the 9008 bulb, which carries a different base type than the 9003 used in prior years.
Because the 9003 and 9008 bulbs have different base configurations, a 9003 bulb from a 2011-2018 model is not a direct physical fit for the 2019 headlight housing, and vice versa.
Both bulb types serve dual-beam functions within a single housing, handling both high and low beam output through separate filaments rather than requiring two separate bulbs per headlight position.
