Additional Notes

The T10 miniature wedge form factor is the sole bulb type used across all listed model years of the Polaris 500 XC tail light specifications, appearing as either the 194 or 906 variant depending on the year.
Both the 194 and 906 bulbs share the same T10 wedge base and 12-volt operating voltage, which means they are physically interchangeable in terms of socket fitment.
Despite their physical compatibility, the 194 and 906 bulbs differ significantly in wattage. The 194 draws 3.78W, while the 906 draws 8W, making them electrically distinct and not functionally interchangeable as direct replacements.
The Polaris 500 XC (2001-2003) uses the 194 bulb for the tail light position, while the 1999-2000 model years use the higher-wattage 906 bulb.
Both bulb types conform to ANSI standards recognized in the United States and Canada, indicating standardized performance and dimensional tolerances within those markets.
The T10 designation refers to a tubular bulb with a width of 10 thirty-seconds of an inch, a common sizing convention used in miniature automotive lighting applications.
