Additional Notes

The 1157 is the sole tail light bulb type listed across all specified model years of the Ski-Doo Summit 700, covering 2000-2001 and 2003.
The 1157 is an ANSI-standardized bulb recognized in both the United States and Canada, operating on a 12-volt system with a dual-filament design rated at 21 watts and 5 watts respectively.
The dual-filament configuration of the 1157 allows it to serve two distinct brightness levels within a single bulb, a characteristic typically associated with combined tail light and brake light functions.
The 1157 uses a BAY15d bayonet base, which is an offset twin-pin mount. The asymmetric pin placement of the BAY15d base prevents incorrect insertion orientation during installation.
The BAY15d base type is not universally interchangeable with all bayonet-style bulbs. Single-filament bayonet bulbs such as the 1156, which use a BAY15s base with symmetrical pins, are not a direct substitute for the 1157 in these applications.
