Additional Notes

The Polaris 600 XC SP tail light specifications reference two distinct ANSI-standard bulb types across its model years: the 194 and the 3157, both rated for 12-volt electrical systems.
The 194 is a miniature wedge bulb classified under the T10 form factor, operating at 12V with a power draw of 3.78W. Its single-filament design suits low-intensity lighting functions such as tail and parking lights.
The 3157 is a dual-filament wedge bulb classified under the T25 form factor, operating at 12V with filaments rated at 27W and 7W respectively. The dual-filament construction allows it to serve two lighting functions within a single housing, typically combining stop and tail light duties.
The 194 bulb is specified for the Polaris 600 XC SP across the 1999-2004 model years, making it the more widely applied of the two bulb types in this fitment range.
The 2005 Polaris 600 XC SP departs from the preceding years by requiring the 3157 bulb rather than the 194. These two bulb types are not interchangeable due to differences in physical size, wattage, and filament count.
The T10 and T25 designations refer to the outer envelope width of the bulb, measured in units of one-eighth of an inch. The T25 of the 3157 is physically larger than the T10 of the 194, which further prevents cross-substitution between the two types.
