Additional Notes

The Polaris Turbo IQ LXT uses the 3157 bulb for brake lighting across the 2011-2014 model years.
The 3157 is an ANSI-standardized bulb type, meaning its specifications are governed by a formal industry standard recognized in both the United States and Canada.
This bulb follows the T25 wedge form factor, a designation that refers to its physical base and envelope shape, which determines physical fitment into the socket.
The 3157 operates on a 12-volt electrical system, consistent with standard automotive and powersports vehicle architecture.
As a dual-filament bulb, the 3157 carries two separate filaments rated at 27 watts and 7 watts, allowing it to serve both a higher-intensity brake function and a lower-intensity running light function within a single housing.
The dual-filament nature of the 3157 means a single-filament substitute would not replicate full functionality in sockets wired to use both filaments.
