The International 5070 uses 1156 and 199 bulb sizes for front turn signal applications and 1157 bulb size for rear turn signal functions. The replacement chart covers 1992 through 1997 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The International 5070 front turn signal uses two distinct bulb types across its model years: the 1156 for 1992-1993, 1995, and 1997, and the 199 for 1994 and 1996.
The 1156 and 199 are both ANSI-standard single-filament bulbs rated at 12V and 21W, sharing the same BA15s bayonet base.
The 199 is a variant of the 1156, meaning the two share the same base type and electrical ratings despite carrying different part designations.
The International 5070 rear turn signal uses the 1157 bulb uniformly across all model years from 1992-1997.
The 1157 is a dual-filament bulb rated at 12V with a 21W main filament and a 5W secondary filament, mounted on a BAY15d bayonet base.
The BAY15d base of the 1157 is not interchangeable with the BA15s base of the 1156 or 199, as the pin offset on a BAY15d base prevents fitment into a BA15s socket.
The dual-filament design of the 1157 allows it to serve both turn signal and running light functions from a single bulb housing at the rear.
All three bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada.
