The International 9200 SBA front turn signal uses a 1156 bulb size while the rear turn signal requires a 1157 bulb size. The replacement chart covers vehicle production spanning 1993 to 1997.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The International 9200 SBA uses the 1156 bulb for the front turn signal and the 1157 bulb for the rear turn signal across the 1993-1997 model years.
The 1156 is a single-filament bulb rated at 12V and 21W, mounted on a BA15s bayonet base, and classified under the ANSI standard applicable in the US and Canada.
The 1157 is a dual-filament bulb rated at 12V with filaments drawing 21W and 5W respectively, mounted on a BAY15d bayonet base, and also classified under the same ANSI standard.
The dual-filament design of the 1157 allows it to serve two lighting functions from a single socket, which is why it is suited to the rear position where both turn signal and running light functions are typically required.
The BA15s base of the 1156 and the BAY15d base of the 1157 are both bayonet-style mounts, but they are not interchangeable. The BAY15d base has offset pins that prevent incorrect installation of a single-filament bulb in a dual-filament socket.
Because the 1156 and 1157 share a similar physical profile but differ in base pin configuration and filament count, substituting one for the other in the 9200 SBA would result in either a fitment failure or loss of a lighting function.
