Additional Notes

The 1157 is the sole tail light bulb type specified for the Ski-Doo MX Z 600 X across all listed model years.
The 1157 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical parameters shared across manufacturers.
This bulb uses a dual-filament design, operating at 21W on the higher-draw filament and 5W on the lower-draw filament, which allows a single bulb to serve both tail light and brake light functions simultaneously.
The 1157 uses a BAY15d bayonet base, a two-pin offset base where the two pins are positioned at different heights to prevent incorrect insertion orientation during installation.
The bulb operates on a 12V electrical system, consistent with standard 12-volt vehicle circuitry.
The specified model years for the MX Z 600 X run from 2001-2006 and 2008-2010, with the 1157 bulb applying uniformly across all of them.
Because the 1157 is an ANSI-standardized type, physically compatible substitutes from different manufacturers are generally available, provided they match the BAY15d base and the 12V, 21W/5W filament ratings.
The dual-filament nature of the 1157 means that a replacement bulb with only a single filament, such as the related 1156 type, would not be a direct functional equivalent for this application.
