Additional Notes

The 3157 is the tail light bulb size specified for the Polaris RZR 570 EPS across the 2017-2019 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 the United States and Canada.
This bulb follows the T25 wedge form factor, which refers to its tapered, wedge-shaped base that seats directly into a socket without requiring a separate bayonet or screw fitting.
The 3157 operates on a 12-volt system and carries a dual-filament design rated at 27 watts for the high-intensity filament and 7 watts for the low-intensity filament, allowing it to serve both brake and running light functions within a single housing.
Because the 3157 is a dual-filament bulb, 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.
