Additional Notes

The 3157 is an ANSI-standardized bulb type recognized across the United States and Canada, operating at 12 volts with a dual-filament design rated at 27 watts for the high-intensity filament and 7 watts for the low-intensity filament.
The dual-filament construction of the 3157 allows a single bulb to serve two distinct brightness levels within one housing, a characteristic that suits brake and tail light functions where separate intensity outputs are required.
The 3157 follows the T25 wedge form factor, a designation that reflects the bulb's physical profile and base type, which determines physical fitment within the socket.
The Polaris Sportsman 450 HO EPS uses the 3157 bulb for brake light applications across the 2017-2019 model years.
Because the 3157 is a dual-filament type, substitution with a single-filament bulb of similar wattage would not replicate the full electrical behavior of the original specification and is not considered a direct replacement.
