The Polaris 600 IQ uses 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2009 through 2012 vehicle 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 specified across all headlight positions for the Polaris 600 IQ, covering model years 2009-2012.
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 serves both the high beam and low beam positions on the Polaris 600 IQ, the same bulb part number applies to both sockets without distinction.
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 uses a P43t base, which is a standardized bayonet-style base with a 43mm flange width, governing physical fitment into the headlight housing.
The 9003 designation follows the ANSI standard as used in the United States and Canada, and it is functionally equivalent to the H4 bulb used under international IEC standards, though the two designations originate from different standardization bodies.
Because the H4 and 9003 share the same physical base and electrical ratings, aftermarket bulbs labeled as either designation are generally interchangeable, though confirming the P43t base specification is advisable before substitution.
