The Polaris 900 Fusion headlight bulb uses a 9003 size for both high beam and low beam applications. The replacement chart covers 2005 to 2006 vehicle production 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 listed headlight positions for the Polaris 900 Fusion, covering both the 2005-2006 model years.
The 9003 is an ANSI-standard halogen bulb recognized in the United States and Canada, operating on a 12-volt electrical system with a dual-filament design rated at 60 watts for high beam and 55 watts for low beam.
Because the 9003 is a dual-filament bulb, a single physical unit serves both the high beam and low beam functions, which accounts for its use across both headlight positions in the Polaris 900 Fusion (2005-2006).
The 9003 uses a P43t base, a bayonet-style mount that is specific to this bulb family and is not interchangeable with single-filament bases such as those found on H1 or H7 bulbs.
The 9003 is functionally equivalent to the H4 bulb used in international markets, sharing the same dual-filament halogen construction and P43t base, though the 9003 designation reflects the ANSI classification system rather than the ECE system used outside North America.
