Additional Notes

The 3157 is a dual-filament T25 wedge bulb rated at 12V with a 27W/8W output, conforming to ANSI standards applicable in the US and Canada. Its dual-filament design allows it to serve two brightness levels within a single housing, which is typical for combined stop and tail light functions.
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 lower wattage reflects its role as a low-intensity marker or tail light source.
The 2004 Polaris 800 XC uses different tail light bulbs depending on seat configuration. The adjustable seat variant takes a 3157 bulb, while the fixed seat variant takes a 194 bulb.
The T25 and T10 designations refer to the outer envelope size of the bulb, with T25 being physically larger than T10. These two bulb types are not interchangeable due to differences in size, wattage, and filament count.
The 2003 800 XC specifies the 194 bulb regardless of seat configuration, aligning it with the fixed seat variant of the 2004 model rather than the adjustable seat variant.
