The Polaris Trail Deluxe high beam and low beam headlight bulbs both utilize a 9003 bulb size for proper illumination. The replacement chart covers vehicle production spanning 1988 to 1992 with corresponding bulb specifications.
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 specified size for both the high beam and low beam headlight positions on the Polaris Trail Deluxe across the 1988-1992 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments, one rated at 60 watts for high beam output and one rated at 55 watts for low beam output.
The 9003 operates on a 12-volt electrical system, which is standard for most powersport and automotive applications in this era.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm flange that positions and locks the bulb into the headlight housing.
The 9003 is classified under the ANSI standard and is recognized in both the United States and Canada under that designation.
Because the 9003 serves both the high beam and low beam positions on the Trail Deluxe, a single replacement bulb type covers both headlight functions on the vehicle.
The 9003 and H4 bulb types share the same dual-filament design and P43t base, making them functionally interchangeable in many applications, though fitment should be confirmed against the housing before substitution.
