Additional Notes

The Suzuki Samurai uses the 1156 bulb size for the back up light across all listed model years, spanning 1986-1995.
The 1156 is an ANSI-standardized bulb type, meaning its physical and electrical specifications conform to a defined North American standard used across the United States and Canada.
The 1156 bulb operates on a 12-volt electrical system and draws 21 watts, which is consistent with standard automotive reverse lighting applications.
The 1156 uses a single-filament design, meaning it serves one lighting function only, as opposed to dual-filament bulbs that can serve two functions such as braking and running light simultaneously.
The BA15s bayonet base on the 1156 features a single locating pin on the side of the base, which distinguishes it from the BA15d base used on dual-filament bulbs. These two base types are not interchangeable despite their similar appearance.
