Ski-Doo MX Z 800 X headlight bulbs utilize a 9003 size for both high and low beam applications. The replacement chart covers 2001 to 2010 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 MX Z 800 X uses the 9003 bulb size for both its high beam and low beam headlights across all model years from 2001-2010.
The 9003 is an ANSI-standard halogen bulb recognized in both the United States and Canada, operating on a 12-volt electrical system with a dual-filament design rated at 60 watts for high beam and 55 watts for low beam.
The dual-filament construction of the 9003 allows a single bulb to serve both the high and low beam functions, which accounts for its use in both headlight positions on this vehicle.
The 9003 bulb uses a P43t base, a bayonet-style fitting with a 43mm collar that physically determines socket compatibility and prevents incorrect bulb installation.
The 9003 designation is the ANSI classification for this bulb type, which is also sold under the European designation H4. The two are electrically identical, though housing fitment should be confirmed before substitution.
