Bulb Size by Year Range

Years	Bulb Size

Description	Bulb Size
ANSI standard (US & Canada). Dual-filament bulb with BAY15d bayonet base. 12V, 21W/5W.	1157

The Ski-Doo Skandic WT uses the 1157 bulb for its tail light across the 1996-2019 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 bulb operates on a 12-volt electrical system and carries a 21W/5W rating, corresponding to its high and low filaments respectively.
The 1157 uses a BAY15d bayonet base, which features two offset pins at different heights to ensure correct orientation during installation and prevent incorrect filament alignment.
The 1157 conforms to ANSI standards recognized in both the United States and Canada, placing it within a widely standardized specification for North American applications.
The BAY15d base of the 1157 is not interchangeable with single-filament bayonet bases such as the BA15s, as the dual-pin offset configuration is specific to dual-filament applications.
