Additional Notes

The Ski-Doo Skandic SWT uses the 1157 bulb for its tail light across the 1997-2019 model years.
The 1157 is a dual-filament bulb, meaning it serves two lighting functions within a single housing, typically a higher-wattage filament for braking and a lower-wattage filament for running light operation.
The 1157 operates at 12 volts with a wattage rating of 21W on the primary filament and 5W on the secondary filament.
The bulb uses a BAY15d bayonet base, which is an offset twin-pin base. The two pins are positioned at different heights to ensure the bulb is inserted in the correct orientation, preventing the filaments from being wired to the wrong circuit.
The 1157 conforms to ANSI standards recognized in both the United States and Canada, placing it within a widely standardized specification used across many vehicle types and manufacturers.
Because the BAY15d base is an offset design, it is not interchangeable with single-filament bayonet bulbs or with the visually similar BA15d base, which uses pins at equal heights.
