Additional Notes

The 1157 is a dual-filament bulb, meaning it contains two separate filaments within a single glass envelope. One filament operates at 21W for the brake function, and the other operates at 5W for the running light function. This design allows a single bulb to serve two lighting roles simultaneously.
The 1157 uses a BAY15d bayonet base, which features two offset pins positioned at different heights on the base. This offset pin arrangement prevents the bulb from being inserted in the wrong orientation, ensuring each filament connects to its correct circuit.
The 1157 is rated at 12V, which is standard for most powersports electrical systems. It is classified under the ANSI standard, meaning its physical and electrical specifications are consistent across manufacturers in the United States and Canada.
The Ski-Doo GSX 380 uses the 1157 bulb size for the brake light position across the 2005-2006 model years.
