Additional Notes

The 3157 bulb is the brake 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 specifications are governed by a recognized North American standard used in both the United States and Canada.
This bulb follows the T25 wedge form factor, which refers to its physical base and envelope shape and determines physical fitment into the socket.
The 3157 operates on a 12-volt system and carries a dual-wattage rating of 27W and 7W, corresponding to its two filaments. The higher-wattage filament serves the brake function, while the lower-wattage filament serves a secondary function such as running or tail light operation.
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.
