Additional Notes

The 3157 is a dual-filament bulb, meaning it contains two separate filaments within a single housing. One filament operates at 27W for the brake or turn signal function, and the other operates at 7W for the lower-intensity running light function.
The 3157 follows the ANSI standard, which is the classification system used in the United States and Canada. This standard defines the bulb's electrical and physical characteristics to ensure consistent performance across compatible applications.
The T25 designation refers to the wedge-style base of the bulb. This base type is inserted and held in place by friction rather than by a bayonet or screw mechanism, which is a common trait in automotive and powersports lighting sockets.
The Polaris Sportsman 110 EFI uses the 3157 bulb for the brake light position across the 2016-2017 model years.
The 3157 operates at 12 volts, which is consistent with standard 12V electrical systems found in powersports vehicles of this type.
The 3157 bulb has known interchangeability considerations. Variants such as the 3057, 3357, and 3457 share the same socket footprint but differ in wattage ratings, which affects brightness and may affect compatibility with the original socket and wiring.
