The Suzuki Sidekick turn signal requires a 1156 bulb size for the lighting system. Data for the specific bulb requirements covers the range from 1996 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Suzuki Sidekick uses the 1156 bulb for both its front and rear turn signals across the 1989-1998 model years.
The 1156 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American industry standard applicable in both the United States and Canada.
The 1156 operates at 12 volts and 21 watts, which is typical for incandescent turn signal applications in passenger vehicles of this era.
The 1156 is a single-filament bulb, meaning it serves only one lighting function per socket, as opposed to dual-filament types such as the 1157, which can serve two functions simultaneously.
The 1156 uses a BA15s bayonet base, where "BA15s" denotes a single-contact bayonet fitting with a 15mm base width. The single-contact design is consistent with the bulb's single-filament construction.
Because the Sidekick uses the same 1156 bulb for both front and rear turn signal positions across all listed model years, the same replacement bulb is interchangeable between both locations on the vehicle.
The 1157 bulb, which shares the same BA15 bayonet family, is not interchangeable with the 1156. The 1157 has a dual-contact base to support its two filaments, and its socket configuration differs from the single-contact BA15s used in the Sidekick.
