Additional Notes

The Polaris Frontier Touring uses the 3157 bulb for the brake light position across the 2003-2005 model years.
The 3157 is an ANSI-standardized bulb type, meaning its specifications are governed by a formal industry standard recognized in the United States and Canada.
This bulb operates on a dual-filament design within a T25 wedge base, where one filament draws 27W for the brake/stop function and a second filament draws 7W for the lower-intensity running light function.
The wedge base format means the bulb is held in its socket by the tension of the base itself rather than by a bayonet or screw mechanism, which is a common trait of T25 bulbs in this application.
The 12V operating voltage of the 3157 is consistent with the standard electrical system voltage found in most production road vehicles and powersports equipment of this era.
Because the 3157 is a dual-filament bulb, substituting it with a single-filament equivalent would result in the loss of either the brake or the running light function, making filament count a critical factor in any replacement selection.
