International S2375 License Plate Bulb Size

Additional Notes

• The 1157 is the license plate bulb size for the International S2375 across the 1984-1988 model years covered in these specifications.
• The 1157 is a dual-filament bulb, meaning it contains two separate filaments within a single glass envelope, each rated at a different wattage.
• The 1157 operates at 12 volts, with filaments rated at 21 watts and 5 watts respectively.
• The 1157 uses a BAY15d bayonet base, a two-pin offset base design that prevents incorrect insertion by positioning the pins at different heights.
• The 1157 carries ANSI standardization, indicating the bulb conforms to specifications recognized across the United States and Canada.
• The BAY15d base is specific to dual-filament bayonet bulbs and is not interchangeable with single-filament bayonet bases such as the BA15s, which shares a similar physical form but differs in pin configuration.
