The Ski-Doo MX Z 380 headlight bulb uses a 9003 size for both high beam and low beam functions. The replacement chart covers 2001 to 2006 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 380 uses the 9003 bulb across all listed model years (2001-2006) for both high beam and low beam headlight positions.
The 9003 is an ANSI-standard designation recognized in the United States and Canada, making it the North American equivalent of the internationally designated H4 bulb type.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit serves both the high beam and low beam functions rather than requiring separate bulbs for each.
The bulb operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a three-pronged bayonet-style mount with a 43mm collar, and fitment depends on this base type matching the socket in the headlight housing.
Because the same bulb size is specified for both the high beam and low beam positions, the MX Z 380 headlight assembly uses a single dual-filament unit per housing rather than a separate bulb for each function.
