Additional Notes

The Polaris Frontier Touring uses the 3157 bulb for its tail light across the 2003-2005 model years.
The 3157 is an ANSI-standardized bulb type recognized across the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared by all compliant manufacturers.
This bulb follows the T25 wedge form factor, which refers to its tapered base design that seats directly into a matching socket without a separate metal base or locking pins.
The 3157 operates on a 12-volt system and carries a dual-filament design rated at 27 watts and 7 watts, where the higher-wattage filament serves the brake or turn signal function and the lower-wattage filament serves the running light function.
Because the 3157 is dual-filament, it is not directly interchangeable with single-filament bulbs such as the 3156, even though those share the same T25 socket type. Installing a single-filament replacement in a dual-filament application results in the loss of one lighting function.
