The Ski-Doo GSX 380 uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2005 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 9003 bulb is a dual-filament halogen type, meaning a single bulb contains two separate filaments to handle both high and low beam functions independently.
The 9003 operates at 12 volts, with a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, which is a standardized bayonet-style fitting with a 43mm base width, governing physical compatibility with the socket.
The 9003 is defined under the ANSI standard, making it the designated specification for the United States and Canadian markets.
The Ski-Doo GSX 380 uses the 9003 bulb for both the high beam and low beam headlight positions across the 2005-2006 model years.
Because the high beam and low beam positions share the same 9003 bulb type, a single replacement bulb serves both functions in this vehicle.
The 9003 bulb is sometimes cross-referenced with the H4 designation, though H4 is the international ECE standard equivalent and the two are not always interchangeable due to differences in base construction and beam pattern certification.
