Additional Notes

The 1157 is the tail light bulb size for the Ski-Doo Freestyle across the 2007-2009 model years.
The 1157 bulb follows the ANSI standard, which is the recognized specification system used in the United States and Canada for automotive and powersports lighting.
As a dual-filament bulb, the 1157 operates two separate filaments within a single envelope, one rated at 21W for the brake or turn signal function and one at 5W for the running light function.
The 1157 uses a BAY15d bayonet base, which features two offset pins at different heights to ensure the bulb is inserted in only one rotational orientation, preventing filament misalignment.
The bulb operates on a 12V electrical system, consistent with standard powersports vehicle electrical architecture.
The BAY15d base type is specific to dual-filament applications and is not interchangeable with single-filament bayonet bases such as the BA15s, which shares a similar physical form but lacks the offset pin configuration required for dual-circuit operation.
