The Polaris Wide Trak high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 1991 to 1993.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 is a dual-filament halogen bulb operating at 12 volts, with a rated output of 60 watts on the high beam filament and 55 watts on the low beam filament, mounted on a P43t base.
Because the 9003 carries two filaments within a single housing, it serves both high beam and low beam functions from one bulb, which is reflected in the Polaris Wide Trak (1991-1993) listing the same bulb size across both sub-parts.
The 9003 designation follows ANSI standards as applied in the United States and Canada, meaning the specification is governed by a defined set of dimensional and photometric requirements rather than manufacturer discretion.
The P43t base is a bayonet-style mount with a 43mm collar, and correct base fitment is a prerequisite for proper seating and electrical contact in the headlight assembly.
The 9003 is electrically and physically equivalent to the H4 bulb used under international ECE standards, though the two designations originate from different regulatory frameworks and packaging may differ between them.
All three model years of the Polaris Wide Trak covered in the specifications, spanning 1991-1993, share an identical 9003 fitment for both beam positions, indicating no change in headlight bulb specification across that production period.
