Additional Notes

The 194 bulb is an ANSI-standard miniature wedge type in the T10 form factor, rated at 12V and 3.78W. Its low wattage reflects its role as a small indicator or marker light rather than a high-output source.
The 3157 bulb is an ANSI-standard dual-filament wedge type in the T25 form factor, rated at 12V with a 27W bright filament and a 7W dim filament. The dual-filament design allows a single bulb to serve two lighting functions, typically stop and tail, within one housing.
Both bulb types conform to ANSI standards applicable in the United States and Canada, meaning they follow a shared specification for base size, voltage, and wattage that ensures consistent fitment across compliant sockets.
The Polaris 500 Classic used the 194 bulb for model years 1999-2004, while the 3157 bulb was specified for 2005-2006. These two bulb types are not interchangeable, as they differ in form factor, wattage, and filament count.
The T10 and T25 designations refer to the outer width of the wedge base, with T25 being physically larger than T10. Attempting to fit a 3157 into a socket sized for a 194 is not possible without modification, and the reverse presents the same incompatibility.
