Additional Notes

The 3157 is the brake bulb size specified for the Polaris RZR 570 across the 2015-2019 model years.
The 3157 is an ANSI-standardized bulb type, meaning its physical and electrical specifications are governed by a recognized North American standard used in both the United States and Canada.
As a dual-filament bulb, the 3157 operates two separate filaments within a single housing, one rated at 27W for high-intensity functions such as braking and one at 7W for lower-intensity functions such as running lights.
The 3157 follows the T25 wedge form factor, a designation that describes the bulb's base and body shape, which determines physical fitment into the socket.
The bulb operates on a 12V electrical system, consistent with standard automotive and powersports vehicle architecture.
Because the 3157 is a dual-filament type, substituting it with a single-filament equivalent would result in the loss of one lighting function, making filament count a critical factor in replacement selection.
