Additional Notes

The 3157 is a dual-filament bulb operating at 12 volts with a 27W filament for high-intensity signaling and a 7W filament for lower-intensity functions, such as running or parking light operation.
The 3157 follows the ANSI standard, meaning its specifications are regulated for consistent performance across compliant products sold in the United States and Canada.
The Polaris Sportsman 570 uses the 3157 bulb in the rear turn signal position for the 2018-2019 model years.
The T25 designation refers to the wedge-style base of the 3157 bulb, which seats directly into a socket without a separate bayonet or screw mechanism. Substituting a single-filament bulb in a dual-filament socket will result in the loss of one lighting function.
