Additional Notes

The Ski-Doo MX Z 380 uses the 1157 bulb for its brake light across the 2001-2006 model years.
The 1157 is an ANSI-standardized bulb type recognized across the United States and Canada.
It is a dual-filament design, operating at 12 volts with a higher-output filament rated at 21 watts and a lower-output filament rated at 5 watts, allowing a single bulb to serve both brake and running light functions.
The 1157 uses a BAY15d bayonet base, which features two offset pins at different heights to prevent incorrect insertion during fitment.
Because the BAY15d base is offset, it is not interchangeable with single-pin or symmetrical dual-pin bayonet bases, such as the BA15s or BAY15s types.
