The Suzuki X-90 turn signal utilizes a 1156 bulb size for the lighting component located on the exterior of the vehicle. Data for the specific bulb 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 1156 is a single-filament bulb built on a BA15s bayonet base, which features a single contact pin offset to one side to ensure correct orientation during installation.
The Suzuki X-90 uses the 1156 bulb size across all front and rear turn signal positions for the 1996-1998 model years.
Operating at 12 volts and 21 watts, the 1156 is rated for the standard automotive electrical systems found in most passenger vehicles of this era.
The 1156 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning the designation refers to a consistent set of electrical and physical characteristics across manufacturers.
Because the X-90 uses the same 1156 bulb for both front and rear turn signals, the same bulb type serves all four turn signal positions on the vehicle.
The single-filament design of the 1156 means it is dedicated solely to one function per socket, distinguishing it from dual-filament bulbs such as the 1157, which serve multiple functions from a single housing.
The BA15s bayonet base is not interchangeable with the BA15d base found on dual-filament bulbs, as the pin configuration differs between the two base types.
