Additional Notes

The 1157 is a dual-filament bulb, meaning it serves two lighting functions within a single unit. The higher-power filament at 21W handles the brake or turn signal function, while the lower-power filament at 5W handles the running or tail light function.
The 1157 operates on a 12-volt electrical system, which aligns with the standard automotive and motorcycle electrical architecture used in the Harley-Davidson FXR Super Glide II.
The 1157 uses a BAY15d bayonet base, a two-pin offset base design. The offset pin placement is a deliberate fitment feature that prevents incorrect insertion, ensuring the two filaments are correctly aligned with their respective circuits.
The 1157 is classified under the ANSI standard, meaning its physical and electrical specifications are standardized across manufacturers in the United States and Canada, making cross-brand replacements generally consistent in performance.
The tail light bulb size for the Harley-Davidson FXR Super Glide II is the 1157 across both the 1982-1983 model years covered in these specifications.
