Additional Notes

The Polaris Trail uses the 194 bulb for its tail light across all listed model years from 1985 to 1999.
The 194 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications rather than being a proprietary part.
It belongs to the T10 miniature wedge form factor, which uses a wedge-shaped base that seats directly into a socket without a separate metal cap or pins.
The bulb operates at 12 volts with a power draw of 3.78 watts, placing it in the low-wattage range typical of indicator and marker lighting rather than primary illumination.
The T10 wedge base is a widely produced format, and the 194 designation is shared across many vehicle makes and models, which reflects broad aftermarket availability.
Because the 194 is defined by the ANSI standard, substitutions should match the T10 wedge base along with the 12V and 3.78W ratings to maintain correct socket fit and circuit load.
