Additional Notes

The 3157 is the sole tail light bulb type listed across all covered model years of the Polaris ACE 500 / 570, spanning 2016-2019.
The 3157 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared across manufacturers.
This bulb is a dual-filament type, which allows a single unit to serve two distinct lighting functions, typically a lower-intensity running or parking light and a higher-intensity brake or stop light.
The 3157 operates on a 12-volt electrical system, consistent with standard automotive and powersports vehicle architecture.
Its two filaments are rated at 27 watts and 7 watts respectively, with the higher wattage filament corresponding to the brighter stop or brake function and the lower wattage filament serving the reduced-intensity circuit.
The bulb follows the T25 wedge form factor, a designation that describes its physical housing shape and base type, which determines physical fitment into the socket.
The 3157 belongs to a family of visually similar bulbs, including the 3156 (single-filament) and 3057, which share the same base but differ in filament count or wattage ratings, making substitution without verification a potential source of incorrect fitment.
