Ski-Doo GSX 800 high beam and low beam headlight bulbs both utilize a 9003 size. The replacement chart covers 2004 through 2015 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ski-Doo GSX 800 uses the 9003 bulb size for both the high beam and low beam headlight positions across the 2004-2008 and 2012-2015 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both the high beam and low beam functions simultaneously.
Because both headlight positions share the same 9003 specification, a single bulb type covers the full headlight assembly on this vehicle.
The 9003 operates at 12 volts, with the high beam filament rated at 60 watts and the low beam filament rated at 55 watts.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm collar, and this base type determines physical fitment into the headlight housing.
The 9003 is defined under the ANSI standard and is recognized in both the United States and Canada, making it a widely available bulb type in North American markets.
The 9003 and H4 bulbs share the same dual-filament halogen design and P43t base, though the 9003 designation follows the ANSI naming convention while H4 follows the ECE convention used in many international markets.
Substituting a single-filament bulb in either headlight socket would not be compatible with the 9003 socket, as the P43t base and dual-filament configuration are specific to that bulb type.
