Ski-Doo Summit 1000 Highmark X Headlight Bulb Size
Ski-Doo Summit 1000 Highmark X high beam and low beam headlight bulbs both utilize a 9003 bulb size for optimal illumination. The replacement chart covers 2005 through 2008 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 is the sole bulb type specified across all headlight positions on the Ski-Doo Summit 1000 Highmark X, covering model years 2005-2008.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both high and low beam functions independently.
Because the 9003 handles both beam functions within one bulb, the high beam and low beam headlight positions on this vehicle share an identical part number across all listed years.
The 9003 operates on a 12-volt electrical system and carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 follows the ANSI standard recognized in the United States and Canada, and it uses a P43t base, which is a specific bayonet-style mounting base that determines physical socket compatibility.
The 9003 bulb type is interchangeable with the HB2 designation, as both refer to the same ANSI-standardized dual-filament halogen specification with a P43t base.
