Additional Notes

The 1157 is an ANSI-standardized bulb used in the United States and Canada, featuring a dual-filament design within a single housing. The two filaments operate at different wattages, 21W for the higher-intensity function and 5W for the lower-intensity function, both running on a 12V circuit.
The 1157 uses a BAY15d bayonet base, a two-pin offset base type. The offset pin placement is a deliberate fitment control, as it prevents the bulb from being inserted in the wrong orientation, which would reverse the filament functions.
The Ski-Doo GTX 380 uses the 1157 bulb for its brake light across the 2005-2006 model years.
