Additional Notes

The Honda Motorcycle XR650L uses the 1157 bulb for the license plate position across the 2015-2019 model years.
The 1157 is an ANSI-standardized bulb type, meaning its physical and electrical specifications are governed by a recognized North American standard used in both the United States and Canada.
The 1157 is a dual-filament bulb, which means it contains two separate filaments within a single glass envelope, each operating at a different wattage.
The two filaments in the 1157 operate at 21 watts and 5 watts respectively, with the higher-wattage filament typically serving a brighter function and the lower-wattage filament serving a reduced-intensity function.
The 1157 operates on a 12-volt electrical system, which is consistent with standard 12V motorcycle electrical architectures.
The 1157 uses a BAY15d bayonet base, a two-pin base type where the two pins are offset at different heights to ensure the bulb is inserted in only one orientation, preventing filament misassignment.
The BAY15d base is specific to dual-filament applications and is not interchangeable with single-filament bayonet bases such as the BA15s, which shares a similar form but lacks the offset pin configuration required for dual-filament operation.
