Additional Notes

The Polaris FS IQ Touring uses the 3157 bulb for brake lighting across the 2007-2009 model years.
The 3157 is an ANSI-standardized bulb type recognized across the United States and Canada, meaning it follows a defined set of electrical and physical specifications shared by all compliant manufacturers.
This bulb operates on a 12-volt system, which is standard for automotive and powersports electrical systems.
The 3157 is a dual-filament type, with one filament rated at 27 watts and a second rated at 7 watts. In brake light applications, the higher-wattage filament typically activates when the brake is applied, while the lower-wattage filament serves as a running light.
The bulb follows a T25 wedge form factor, which refers to its tapered base design that seats directly into a socket without a separate metal base or bayonet pins.
Because the 3157 is a dual-filament bulb, single-filament substitutes of similar wattage are not electrically equivalent and would not replicate the same brake and running light behavior.
