Additional Notes

The 3157 is the tail light bulb size for the Polaris Sportsman 450 HO EPS across the 2017-2019 model years.
The 3157 is a dual-filament bulb, meaning it serves two lighting functions within a single unit, typically handling both running light and brake light duties through separate filaments rated at 7W and 27W respectively.
The bulb operates on a 12V electrical system, which is standard for most powersports and automotive applications.
The T25 designation refers to the bulb's wedge-style base, which is a push-in type that does not require a separate socket lock or twist to seat.
The 3157 follows ANSI standardization, meaning it conforms to a defined specification recognized across the United States and Canada, which governs its electrical and physical characteristics.
Because the 3157 is a dual-filament type, substituting it with a single-filament equivalent such as the 3156 would result in the loss of one lighting function and is not a compatible replacement.
