The Polaris 440 IQ high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 2005 to 2007.
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 listed across all positions in the Polaris 440 IQ specifications, covering both high beam and low beam headlight applications for the 2005-2007 model years.
The 9003 is a dual-filament halogen bulb, meaning a single physical bulb contains two separate filaments: one rated at 60W for high beam output and one at 55W for low beam output.
Because the 9003 serves both the high beam and low beam positions in the Polaris 440 IQ, each headlight assembly uses one bulb to perform both lighting functions rather than requiring separate bulbs for each beam.
The 9003 operates on a 12V electrical system and uses a P43t base, which is a bayonet-style mount with a 43mm collar width.
The 9003 is designated as an ANSI standard bulb applicable in the United States and Canada. It is physically and electrically equivalent to the H4, which is the international designation for the same bulb type, and the two are generally interchangeable.
