Additional Notes

The T10 wedge bulb (size 168) operates at 12 volts with a power draw of 4.9 watts, classifying it as a low-output miniature lamp typically used in parking, marker, or courtesy lighting roles.
The T25 wedge bulb (size 3157) operates at 12 volts with a dual-filament configuration rated at 27 watts and 7 watts, where the higher-wattage filament serves braking or turn functions and the lower-wattage filament serves a running light function.
Both bulb types conform to ANSI standards applicable in the United States and Canada, indicating standardized base dimensions and electrical ratings across manufacturers.
The Polaris Sportsman 570 used the 3157 bulb for tail light fitment across the 2015-2017 model years, while the 2018-2019 model years required the 168 bulb instead.
The 168 and 3157 are not interchangeable. The T10 and T25 wedge bases differ in physical size, and the single-filament 168 cannot replicate the dual-filament behavior of the 3157.
