Polaris 600 XCR Tail Light Bulb Size

The Polaris 600 XCR tail light requires bulb size 906 or 194 depending on the specific version of the snowmobile. Data for the bulb size covers the range from 1994 to 1998.

Additional Notes

The Polaris 600 XCR tail light specifications reference two bulb types across the listed model years: the 906 and the 194. Both are classified under the ANSI standard applicable in the US and Canada, and both share the miniature wedge form factor designated T10.
The T10 wedge base is a connectionless design where the glass envelope itself acts as the contact point, seating directly into a wedge-style socket without a separate metal base or pins.
Although the 906 and 194 bulbs share the same T10 wedge base and 12-volt operating voltage, they are not interchangeable. The 906 operates at 8 watts, while the 194 operates at 3.78 watts, representing a meaningful difference in power draw and light output.
The 1997-1998 Polaris 600 XCR tail light position calls for the 906 bulb. Installing the lower-wattage 194 in its place would result in reduced brightness relative to the original specification.
The 1994-1996 model years specify the 194 bulb for the tail light position. Substituting the higher-wattage 906 could place unintended electrical load on the socket and wiring circuit designed around the 194 rating.
The shared T10 physical form between the two bulb types means a substitution is physically possible without modification, making the wattage difference a non-obvious but critical fitment consideration.
