Additional Notes

The 194 bulb is a miniature wedge type (T10) operating at 12V with a 3.78W output. It carries a single filament and conforms to ANSI standards for the US and Canadian markets. The Polaris Sport Touring used this bulb for its tail light across the 1995-1999 model years.
The 1157 bulb uses a BAY15d bayonet base and carries dual filaments rated at 21W and 5W on a 12V circuit. The higher-wattage filament typically serves the brake light function, while the lower-wattage filament handles the running light. This bulb also meets ANSI standards for the US and Canadian markets.
The Sport Touring used the 1157 for its tail light across the 2000-2003 model years, making it the most frequently specified bulb across the listed range.
The 3157 is a dual-filament wedge bulb in the T25 form factor, rated at 12V with filaments at 27W and 7W. It conforms to ANSI standards for the US and Canadian markets and was specified for the 2004 Sport Touring tail light.
The 3157 and 1157 are both dual-filament bulbs operating on 12V circuits, but they differ in base type and wattage. The 3157 uses a wedge base while the 1157 uses a BAY15d bayonet base, making the two types physically non-interchangeable despite their functional similarity.
The shift from the 194 single-filament bulb to the dual-filament 1157 between the 1999 and 2000 model years represents a change in both the electrical load and the base type of the tail light assembly.
