Additional Notes

The Ski-Doo MX Z 380 uses the 1157 bulb for its tail light across the 2001-2006 model years.
The 1157 is an ANSI-standardized bulb type recognized in both the United States and Canada.
It is a dual-filament bulb, meaning it contains two separate filaments within a single envelope, one rated at 21W and the other at 5W, allowing it to serve both stop and running light functions.
The 1157 uses a BAY15d bayonet base, which features two offset pins at different heights to prevent incorrect installation of a single-filament substitute.
The bulb operates on a 12V electrical system, consistent with standard automotive and powersports vehicle wiring.
Because the 1157 is dual-filament, substituting a single-filament bulb such as the 1156 would result in the loss of one lighting function, as the 1156 shares the same bayonet base style but lacks the second filament.
