Additional Notes

The 3157 is a dual-filament T25 wedge bulb rated at 12V with a 27W high filament and 7W low filament, conforming to ANSI standards for the US and Canada. Its dual-filament design allows it to serve both braking and running light functions within a single housing.
The 194 is a single-filament T10 miniature wedge bulb rated at 12V and 3.78W, also conforming to ANSI standards for the US and Canada. Its significantly lower wattage reflects a simpler, non-dual-function role compared to the 3157.
The two bulb types are not interchangeable. The T25 and T10 wedge bases differ in physical size, and the wattage and filament configurations are incompatible between the 3157 and 194.
The Polaris 800 XC SP used the 194 bulb across the 2001-2003 model years, as well as in the 2004 model year when equipped with a fixed seat.
The 3157 bulb applies to the 2005 model year and to the 2004 model year specifically when the vehicle is equipped with an adjustable seat, indicating that seat configuration directly determines tail light bulb fitment in the 2004 model year.
