Additional Notes

The 1157 is an ANSI-standardized bulb type recognized across the United States and Canada, operating at 12 volts with a dual-filament design rated at 21 watts and 5 watts respectively.
The dual-filament construction of the 1157 allows a single bulb to serve two distinct brightness levels, a characteristic that suits combined stop and tail light functions within one housing.
The Ski-Doo Freestyle uses a BAY15d bayonet base on its brake bulb, a base type that features two offset pins to prevent incorrect insertion orientation.
The 1157 bulb is specified for the Ski-Doo Freestyle across the 2007-2009 model years, indicating a consistent brake light fitment across that production span.
The BAY15d base is not interchangeable with single-filament bayonet bases such as the BA15s, as the pin offset and filament count differ between the two types.
