Additional Notes

The 1157 is a dual-filament bulb operating at 12 volts, with filaments rated at 21 watts and 5 watts respectively. The higher-wattage filament serves the brake or turn signal function, while the lower-wattage filament handles the running light function.
The 1157 uses a BAY15d bayonet base, a two-pin offset base design that prevents incorrect insertion by positioning its two pins at different heights along the base.
The 1157 designation follows the ANSI standard used in the United States and Canada, establishing consistent electrical and physical specifications across manufacturers.
The Ski-Doo GTX 800 uses the 1157 bulb for the tail light position across the 2006-2007 model years.
