The Polaris XLT SP high beam and low beam headlight bulbs both use a 9003 size. The replacement chart covers vehicle production years from 1998 to 1999.
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 serve two distinct lighting functions.
Operating on 12 volts, the 9003 draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a three-pin bayonet-style mount that physically locks the bulb into the housing at a fixed rotational position.
The 9003 designation follows the ANSI standard recognized in both the United States and Canada.
On the Polaris XLT SP, the 9003 bulb serves both the high beam and low beam headlight positions across the 1998-1999 model years.
Because the high beam and low beam positions share the same bulb type, a single 9003 bulb replacement applies to both functions rather than requiring separate part numbers for each position.
The 9003 and H4 bulbs share the same dual-filament halogen design and P43t base, though the 9003 is the ANSI-designated version while H4 follows the ECE standard; fitment compatibility between the two depends on the specific housing design.
