Additional Notes

The 1156 bulb is the most frequently specified backup light bulb for the International 5000, appearing in five of the six model years covered: 1992-1993 and 1995-1997.
The 1156 is an ANSI-standard single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base, which uses a single contact pin offset to one side to ensure correct orientation during installation.
The 199 bulb is specified for the 1994 International 5000 backup light position and shares the same ANSI classification, BA15s bayonet base, 12V rating, and 21W output as the 1156.
The 199 is classified as a variant of the 1156, meaning the two bulbs share the same fundamental electrical and mechanical characteristics despite carrying different part numbers.
Because the 1156 and 199 share the same base type and electrical ratings, the physical and functional overlap between them is a relevant consideration when sourcing a replacement for the 1994 model year.
