The Polaris 600 PRO X high beam and low beam headlight bulbs both utilize a 9003 size. The replacement chart covers vehicle production spanning 2001 to 2004.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Polaris 600 PRO X uses the 9003 bulb size across both its high beam and low beam headlight positions for the 2001-2004 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 both the high beam and low beam positions in the 600 PRO X share the same 9003 specification, a single bulb type serves both lighting functions through its two filaments rather than requiring separate bulbs for each beam.
The 9003 bulb uses a P43t base, which is a bayonet-style mount with a 43mm collar. This base type determines physical fitment and is not interchangeable with other base configurations even when voltage and wattage ratings may otherwise match.
The 9003 designation is the ANSI classification for what is internationally marketed as the H4 bulb. While these two designations refer to functionally equivalent bulbs, labeling differences between markets can affect packaging and sourcing.
The consistent use of the 9003 specification across all four model years covered in the specifications means that a single replacement bulb type applies to the entire 2001-2004 production range of the 600 PRO X for both beam positions.
