Additional Notes

The Suzuki Sidekick uses the 1156 bulb for the back up light across all listed model years, spanning 1989-1998.
The 1156 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized industry standard used across the United States and Canada.
The 1156 is a single-filament bulb, which distinguishes it from dual-filament types such as the 1157. Single-filament bulbs serve only one lighting function rather than two.
The 1156 uses a BA15s bayonet base, where "BA15s" denotes a bayonet mount with a 15mm base width and a single contact pin. This base type requires a matching socket and is not interchangeable with double-contact bayonet bases such as the BA15d.
The 1156 operates at 12 volts and draws 21 watts, which is consistent with standard automotive electrical systems.
