Additional Notes

The Ski-Doo Expedition Sport uses the 1157 bulb across all listed model years from 2006-2019 for the tail light position.
The 1157 is a dual-filament bulb, meaning it serves two lighting functions within a single housing, typically handling both the running light and the brake light through separate filaments rated at 5W and 21W respectively.
This bulb operates on a 12V electrical system, which is standard for most powersport vehicles in this category.
The 1157 uses a BAY15d bayonet base, a two-pin offset base design that prevents incorrect installation by ensuring the pins are not symmetrically positioned.
The 1157 designation follows ANSI standardization recognized in both the United States and Canada, meaning bulbs sold under this number conform to a consistent specification regardless of manufacturer.
Because the 1157 is a dual-filament type, single-filament substitutes such as the 1156 are not interchangeable, as they lack the second filament required for full tail light function.
