Bulb Size by Year Range

Years	Bulb Size
2003-2005	3157

Description	Bulb Size
ANSI standard (US & Canada). Dual-filament wedge bulb (T25). 12V, 27W/7W.	3157

The 3157 is an ANSI-standardized bulb type recognized across the United States and Canada, operating on a 12-volt system with a dual-filament design rated at 27 watts for the primary filament and 7 watts for the secondary filament.
The dual-filament construction of the 3157 allows it to serve two lighting functions within a single housing, with the higher-wattage filament typically handling braking or turn signal output and the lower-wattage filament handling running light output.
The 3157 follows the T25 wedge form factor, a designation that describes the bulb's base and body shape as used in the ANSI classification system.
The Polaris 800 Touring uses the 3157 bulb for its tail light across the 2003-2005 model years.
The 3157 shares its T25 wedge base with several related bulb types, including the single-filament 3156, which is not interchangeable in applications requiring dual-filament operation such as combined brake and running light functions.
