Additional Notes

The 1157 is the brake bulb size for the Harley-Davidson FXR Super Glide II across the 1982-1983 model years.
The 1157 is an ANSI-standardized bulb type used in 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 brightness levels within a single housing, with the higher-wattage filament typically handling the brake or turn signal function and the lower-wattage filament handling the running light function.
The 1157 uses a BAY15d bayonet base, a two-pin offset base type that physically prevents incorrect insertion by positioning its two pins at different heights, which is a built-in fitment control against substituting single-filament bulbs with identical base widths.
