Additional Notes

The 3157 is a dual-filament T25 wedge bulb rated at 12V with a 27W/7W power draw, where the higher wattage filament serves the brake or running function and the lower wattage filament serves the secondary lighting function.
The 194 is a single-filament T10 miniature wedge bulb rated at 12V and 3.78W, a significantly lower output than the 3157, reflecting its use in lower-intensity tail light applications.
Both bulb types conform to ANSI standards recognized in the United States and Canada.
The 2004 Polaris Frontier Classic uses different tail light bulbs depending on seat configuration: the 3157 fits the Adjustable Seat variant, while the 194 fits the Fixed Seat variant.
The 3157 and 194 are physically and electrically distinct bulbs. The T25 and T10 designations indicate different body sizes, and their wattage ratings differ substantially, making them non-interchangeable.
The 2003 Polaris Frontier Classic specifies only the 194 bulb for the tail light, with no seat-based variant distinction present in that model year.
