The Ski-Doo Summit 1000 Highmark uses 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2005 to 2007 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 listed across all headlight positions for the Ski-Doo Summit 1000 Highmark, covering both high beam and low beam functions for the 2005-2007 model years.
The 9003 is a dual-filament halogen bulb, meaning a single physical bulb contains two separate filaments: one rated at 60 watts for high beam output and one rated at 55 watts for low beam output.
The 9003 operates on a 12-volt electrical system and uses a P43t base, which is a bayonet-style mount with a 43mm collar.
The 9003 follows the ANSI standard as recognized in the United States and Canada, distinguishing it from the functionally similar H4 bulb, which follows ECE standards used in many other markets. Although the 9003 and H4 share the same dual-filament halogen design and P43t base, they are not certified as interchangeable across all applications due to differing regulatory standards.
