Additional Notes

The International 7100 uses the 1157 bulb for its license plate position across the 1992-1995 model years.
The 1157 is a dual-filament bulb, meaning it contains two separate filaments within a single envelope, each operating at a different wattage.
The 1157 operates at 12 volts, with filaments rated at 21 watts and 5 watts respectively, reflecting its dual-filament design.
The 1157 uses a BAY15d bayonet base, a two-pin offset base that prevents incorrect insertion by positioning the pins at different heights.
The 1157 conforms to ANSI standards and is recognized in both the United States and Canada, placing it within a widely distributed specification framework.
Because the 1157 is a dual-filament type, substituting it with a single-filament equivalent such as the 1156 would not be electrically or functionally interchangeable, even though both share a bayonet-style base.
