The Polaris 550 Classic uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production years spanning 2002 to 2008.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 is a dual-filament halogen bulb, meaning a single unit contains two separate filaments: one rated at 60W for high beam operation and one rated at 55W for low beam operation.
The Polaris 550 Classic uses the 9003 bulb for both its high beam and low beam headlight positions across the 2002-2008 model years, with a single bulb type serving both lighting functions simultaneously.
The 9003 bulb operates on a 12V electrical system and uses a P43t base, which is a bayonet-style mount with a 43mm collar that physically locks the bulb into the housing.
The 9003 designation is an ANSI standard recognized in the United States and Canada. It is functionally equivalent to the European H4 bulb, though the two designations originate from different standardization bodies and packaging may differ by region.
Because the same 9003 bulb specification applies to both the high beam and low beam positions, a single replacement bulb services both functions in the Polaris 550 Classic headlight assembly.
