The Polaris Frontier Touring high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 2003 to 2005.
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 for the Polaris Frontier Touring across all listed model years and headlight positions.
The 9003 is a dual-filament halogen bulb, meaning a single unit contains separate filaments for both high and low beam operation, which accounts for its use in both headlight positions on the Frontier Touring.
The bulb 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, a standardized bayonet-style fitting that determines physical socket compatibility in the vehicle's headlight housing.
The 9003 designation follows the ANSI standard used in the United States and Canada, which governs the bulb's electrical and physical specifications.
The same 9003 bulb specification applies to the Polaris Frontier Touring across the 2003-2005 model years, covering both the high beam and low beam headlight positions without variation.
The 9003 is functionally equivalent to the H4 bulb type used under international standards, though fitment interchangeability between the two depends on socket and housing design in the specific vehicle application.
