Additional Notes

The Ski-Doo Mach Z uses the 1157 bulb across all listed model years from 1996 to 2007, with the exception of 2004 and 2005, which are not present in the specifications.
The 1157 is an ANSI-standardized bulb type 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 operates on a 12-volt system and carries a dual-wattage rating of 21W and 5W, corresponding to its two separate filaments, which serve high-intensity and low-intensity functions respectively.
The dual-filament design of the 1157 allows a single bulb to handle both brake light and running light functions within one housing, a common arrangement in tail light assemblies.
The 1157 uses a BAY15d bayonet base, which is an offset twin-pin mount. The asymmetric pin placement of the BAY15d base is a physical keying feature that prevents incorrect filament orientation during installation.
Because the BAY15d base is not interchangeable with single-filament bayonet bases such as the BA15s, substituting a single-filament bulb in a dual-filament socket would result in loss of one lighting function.
The consistent use of the 1157 across the 1996-2007 model years indicates that replacement bulbs sourced for any one of these years are electrically and physically compatible with the others listed in the specifications.
