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.
The 1157 is a dual-filament bulb, which means it contains two separate filaments within a single envelope, allowing it to serve both a lower-intensity running light function and a higher-intensity brake light function from one unit.
The bulb operates at 12 volts and carries a wattage rating of 21W for the high-intensity filament and 5W for the low-intensity filament, reflecting the distinct power draw of each filament during operation.
The 1157 uses a BAY15d bayonet base, a two-pin offset base design where the two pins are positioned at different heights to prevent incorrect insertion, ensuring the filaments are oriented correctly within the housing.
The BAY15d base is a widely used standard in automotive and powersports lighting, meaning 1157 bulbs are broadly available as direct replacements from multiple manufacturers.
Any replacement bulb for this application must match the BAY15d base configuration specifically, as visually similar bayonet bases with symmetrical pin placement are not interchangeable with the offset BAY15d design.
