Additional Notes

The 3157 is an ANSI-standard bulb recognized across the United States and Canada, placing it within a widely distributed specification category.
The Polaris FST IQ Cruiser uses the 3157 bulb for brake lighting across its 2007-2008 model years.
The 3157 is a dual-filament bulb, meaning it contains two separate filaments within a single housing, one rated at 27W for the brake or turn function and one at 7W for the running light function.
The T25 designation refers to the bulb's wedge-base form factor, which is a push-in base type that does not use a bayonet or screw fitting.
Operating voltage is 12V, consistent with standard automotive electrical systems.
Because the 3157 is a dual-filament type, 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.
